Somebody Built Cairns on the Wrong Ridge, and I Followed Them

Fair warning: I am not a storyteller. I am a charter. Twelve years in emergency departments will do that to you. You learn to write down what happened, when it happened, what you did about it. So this is going to read like a chart in places. Times are approximate unless I say otherwise, and where they're exact it's because I wrote them down that evening in the little waterproof notebook I keep in my hip belt pocket, which I have been doing on every trip since 2015 and which I am looking at right now on my kitchen table in Denver.

Some context on me, because I think it matters for how you weigh this. I'm 33, male, ER nurse at a large hospital in the Denver metro that I'm not going to name because we were in the middle of some union stuff at the time and I don't need this post showing up in anybody's search results next to my employer. I've been backpacking solo since I was 24. Not casually. I plan the way I chart. Every trip gets a sheet: route by day, mileage by segment, water sources with a confidence rating, bail points with the mileage to each, expected camps with alternates, sunset and civil twilight times, and a gear list with weights to the tenth of an ounce. Base weight for this trip was 17.4 pounds. I can still tell you that without looking.

The trip was five days in a wilderness area in western Wyoming, September 2022. I'm not going to name the wilderness or the trailhead. Partly that's the usual thing where you don't blow up a quiet place, and partly it's that I don't love the idea of anyone going and standing where I stood, which I recognize is not a rational sentence, and I'm writing it anyway. I'll call the trailhead Burnt Meadow, because there's a meadow and it burned. The route was a lollipop: up a creek drainage I'll call Tepee Creek, over a divide on a talus ramp, three high lakes basins, down a second drainage, back to the car. About 41 miles total. I'd done pieces of it in 2019 with my friend Marcus, who matters to this story zero percent, I just want it on record that I wasn't navigating blind. I knew the country.

September was late for that elevation but 2022 was a dry fall and the forecast was stable high pressure, cold nights, warm days. I took the trip dates off a block of PTO I'd had approved since June. I'd been off for four days before I even drove up. My last shift before the trip was a Tuesday and it was boring, which in my line of work is a gift. One ankle fracture, two chest pains that were reflux, a psych hold that transferred out smooth. I went home and packed and my pack sat by the door for three days like a dog that knows.

My wife Erin and I have a system, and the system also matters. I carry a Garmin inReach Mini 2. Every evening at camp I send a preset check-in that hits her phone and email with my coordinates. The preset says OK CAMP ALL GOOD. If plans change I type a custom message. If she doesn't hear from me by 2100 she waits until 0800 the next morning, and if there's still nothing she calls the county sheriff, whose non-emergency number is on a card on our fridge along with my route sheet. We built this protocol together after a trip in 2017 where my SPOT device ate batteries and she spent a night thinking about widowhood. We don't improvise on it. Neither of us. I want that established early because of what happens on day four.

I drove up on Sunday, September 11. I remember the date because gas in Rawlins had a 9/11 memorial thing on the marquee under the price. I slept in the back of the 4Runner at a dispersed site about six miles from the trailhead, ate a gas station burrito I had no business eating, and was at Burnt Meadow by 0730 Monday morning. Frost on the split-rail fence by the stock ramp. Three vehicles in the lot: a newer Tacoma with Idaho plates, a Subaru with a cracked windshield and one of those oval 26.2 stickers, and a horse trailer with no truck attached to it.

There was a couple at the trailhead when I got there. Late fifties, maybe. Matching trekking poles, the man in a cotton hoodie I judged him for. They had a blue heeler mix that came over and leaned on my leg while I was signing the register, and the woman said something like, he does that, he picks a person, and I said he picked right, and gave the dog my knuckles to smell. The dog's name was Banjo. I know that because they said it about nine times. Banjo, leave it. Banjo, water. Banjo, load up. They were doing an out-and-back to the first lake, one night. Nice people. Utterly ordinary.

The register at Burnt Meadow is the standard Forest Service kind, a metal lectern box with a hinged lid and a coil pen and a sheet with columns: date, name, group size, destination, nights out. I filled mine in. September 12. My last name, first initial. Party of 1. The lakes basin, 4 nights. I remember the pen skipped and I had to scribble in the margin to get the ink going, and my scribble is on that page. That page is in a Ziploc bag in a file box in my closet now, and we'll get to why, and I want to say here at the top that I know taking it was wrong. You don't have to tell me. I've been told.

Day one was clean. I want to give you a normal day first so you have a baseline, because that's how you read a rhythm strip. You need the normal beats to see the ectopy.

The Tepee Creek trail climbs gradually through lodgepole for the first four miles, then breaks into a series of meadows where the creek slows down and braids. I filtered a liter at the second meadow at around 1030, ate a tortilla with peanut butter standing up, and kept moving. Saw the couple and Banjo once more around mile three. I went upstream twenty yards and rock-hopped and waved and that was that. Two other parties passed me headed out, a solo woman with an enormous external frame pack who looked like she'd been out for weeks, and two guys my age moving fast with trail runners and running vests, the fast-and-light guys, one of whom said the ramp still had good weather on it yesterday. The horse party I never saw, though I saw their apples. Someone had been feeding cut apples to their stock and there were bright white-and-red slices in the manure line for a mile.

At lunch I did feet. This is procedure and I do it whether or not anything hurts. So: boots off, socks off, air the feet, check heel, ball, pinky toe, between toes. Day one I had one hot spot starting on the left heel. Leukotape over clean dry skin, sock seam rotated, done. Ninety seconds of prevention. I'm telling you this partly because it's what I do and partly because on day five I ran two miles on that ankle and the state of my feet became briefly relevant, and mostly because the blister care is the kind of thing that goes nowhere and I promised myself I'd write this the way it actually was, including the parts that don't pay off.

I made camp one at the head of the third meadow at 1610, small bench of dry ground above the creek, good drainage. I rigged my bear hang before dinner while there was light, which is my habit. There's grizzly presence in that country, not thick, but present, and I do a full PCT-style hang, and I finish the whole thing with the same sequence every time: marlinspike toggle on a clove hitch, then I back it up with two half hitches around the standing line because a ranger in the Winds watched me do a lazy hang in 2016 and shamed me so thoroughly that the shame became the system. My half hitches are ugly. I want that on the record now, it matters later. They hold, but they're ugly, I snug them with a little twist I picked up from nobody, it's just a bad habit with tenure, and if you showed me a photo of my own finished backup hitches next to a stranger's I could pick mine out of a lineup.

Dinner was the beef stroganoff Mountain House because I am a creature of habit and it's the only one that doesn't taste like packaging. Sent the inReach preset at 1902. OK CAMP ALL GOOD. The device shows the little swoosh when the message goes, and then Erin's reply came back about twenty minutes later, a thumbs up and the word stroganoff with a question mark, because she knows me. That exchange is in the Garmin app history with timestamps and I've screenshotted it, and the folder those screenshots live in is called WYOMING SEPT 22 and I open it about once a month.

I slept fine. That's a pertinent negative. No wind event, no animal activity, nothing on the line in the morning, frost on the fly, oatmeal. Packed up, policed the site, left at 0805.

I should say something about my phone, because it comes up. I keep it in airplane mode the whole trip, it's the camera. There's no service in that country anyway, except, and this is real, one spot on the divide where you can sometimes catch a single bar of LTE that sneaks up some corridor from the highway forty miles south, the fast-and-light guys had mentioned it like a landmark, the bar, ha. The reason I mention the phone is that back home the hospital was gearing up for a strike authorization vote that week. Our unit chat had been going off for a month, and one of the last texts I got before I lost service on the drive up was from my coworker Vic, who is a 25-year veteran of that ER and was going through a divorce at the time in the most Vic way possible, which is to say silently and then all at once, and his text said VOTE THURSDAY DON'T FORGET TO BE MAD, and I laughed out loud alone in the truck. I'm putting Vic and the vote in here because both of them were live threads in my head that week. Neither of them has anything to do with what happened. Vic's fine, by the way. He kept the Bronco, she kept the house, he seems okay.

Day two is where the chart starts.

The trail leaves Tepee Creek at about mile nine and climbs to the divide on what my map calls a ramp and what your legs call a punishment, a long rising traverse across a talus field maybe three quarters of a mile wide, big stable blocks, the kind of talus you can actually walk on if you keep your rhythm. The trail through it is obvious. The tread is beaten into the gravel between the blocks, there are old blaze posts at the top and bottom, and the line of it is visible from either end the way a scar is visible on skin. You could navigate it in fog. Nobody who has ever walked on a trail could lose this trail.

At approximately 1115, I noticed a cairn about forty yards upslope of the trail. Then another beyond it. Then a third, higher, near the base of a rib of broken rock. Three cairns, spaced maybe sixty or seventy yards apart, forming a line that left the trail at a shallow angle and climbed toward a notch in the ridge crest that my map did not name and my route did not use.

Cairns are normal. I want to be fair here, because I've spent two years being fair about this. High routes get cairned, bored people stack rocks, some drainages are practically sculpture gardens. What stopped me was three things, and I noted all three at the time, standing there with my thumbs in my shoulder straps.

First, they were well built. Not the six-stone piles day hikers leave. These were knee-high, tapered, big flat foundation stones with the load centered, the kind of cairn a trail crew builds when they mean for it to outlive them. Second, the trail there needs no cairns and has none, none on the tread itself, none marking the line, so someone had chosen to build serious navigation aids pointing away from an obvious route. Third, and this is the one I keep coming back to, the foundation stones were dark at the base. Wet. It hadn't rained in nine days, I knew that from the forecast history I check before every trip, but rocks that have sat in talus a long time have a bathtub ring of dust and lichen where they touch, and rock that's been freshly turned shows its underside, damp and dark, for a day, maybe two in that sun. These bases were dark. Somebody had built them recently. Possibly that morning.

Now, the honest version, since we're voting on my honesty: I was forty yards from the nearest one when I noticed the dark bases, and forty yards is far to be calling rock damp. I know that. I walked up to the first cairn to check, and up close, yes, the underside edges of the foundation stones were damp to the touch, I put my finger on it, cold and wet like the underside of a flowerpot. But the second and third cairns I did not walk to, and in my notebook that night I wrote all three wet based, which is exactly the kind of inference-dressed-as-observation I would flag in someone else's chart. So take that one at two-thirds strength. First cairn wet, confirmed by touch. Other two, presumed.

I took photos. Four of them, timestamped 11:21 to 11:24 on my phone, and one more where I put my trekking pole next to the first cairn for scale. Then I did the thing you do, I sighted along the line of them. The three cairns bore off at what I later measured on the map as roughly 310 degrees, up toward that unnamed notch. Consistent bearing. Not wandering, not decorative. A line with intent, the way an IV line has intent.

And then I ignored them, because the explanation was sitting right there and it was fine. Somebody is scouting an off-trail route to the notch. People do that. I remember actually saying out loud, huh, and then walking on, and I remember that the huh felt complete. Triage: not my patient. I made the divide at 1250, ate lunch in the wind with my back against a blaze post, and dropped into the first lakes basin on the far side, and the afternoon was so good it felt like a paid advertisement for being alive. Golden trout rising in the second lake. I don't fish anymore but I sat and watched the rings.

Camp two, 1545, on the bench above the second lake at about 10,600 feet. Hang went up at 1700 in the only decent tree, a whitebark a hundred yards east of the tent, my ugly hitches and all. Dinner, notebook, inReach preset at 1858. OK CAMP ALL GOOD. Erin thumbs-upped. The stars at that elevation in September are a medical event of their own. In my notebook that night, under the day's mileage and water notes, I wrote: 3 new cairns on ramp, well built, wet based, bearing ~310 toward notch, no cairns needed there. Photo'd. Weird but fine.

Weird but fine is a phrase I use at work. The heart rate that's 61 and then 91 and then 61 in a patient who feels great. You chart it, you don't act on it. The whole skill, the entire thing they can't teach you in school, is knowing the difference between weird but fine and the quiet front edge of a thing that has already decided what it's going to do to you, and the humbling truth of my profession is that sometimes you only ever find out which one it was in retrospect.

I slept fine on night two, mostly. I woke once, around 0200 I'd guess, to what I logged the next morning as rockfall, distant, single event. One clatter, somewhere up toward the divide, the sound talus makes when it shifts, which talus does all on its own, all the time, especially with freeze-thaw working on it. I listened for maybe two minutes, heard the lake lapping and nothing else, and went back to sleep. Freeze-thaw. Rocks fall. If you want a night sound to hang your vote on, I'd honestly rather you didn't pick this one.

Day three. I've written this part so many times, in my head and twice in a notes app I later deleted, that I'm going to slow way down and just walk you through it in order, because order is the only thing I have to offer against the other explanations, including the explanation that I'm lying, which, fair, that's the game here.

The plan for day three was the high traverse: leave the second lake, cross a low saddle into the middle basin, work around two more lakes, then over a second saddle and down into the head of the far drainage, which I'll call Slide Creek, camp at the top of it. Eight and a half miles, most of it above 10,000 feet, and the middle section crosses a series of benches and slabby shoulders where the trail goes thin. Not gone. Thin. It's marked on the map as a maintained trail and it mostly is, but on slickrock and short grass a trail doesn't hold a tread, so for maybe two miles the route is carried by cairns. Old ones. Proper ones. Lichen-covered, sunk into the ground on their own settled bases, some of them with a whitebark limb stuck in the top gone silver with years. That's normal country for cairns and I'd walked it before with Marcus in 2019 and never once thought about the spacing, because you don't think about the spacing, the same way you don't think about your own breathing until someone says the word breathing.

I left camp at 0750. Hang was untouched that morning, for the record. Crossed the first saddle around 0900, and the middle basin opened up below with the two lakes lying there like dropped coins, and I felt great. I want that in the chart too. No dread. I was eating a Snickers on a rock at 0915 with zero premonitions of any kind.

The first cairn on the traverse section came up around 0945, and it was new.

Same build as the ramp cairns. Knee-high, tapered, flat foundation, load centered. Sitting six feet off the line of the old route, next to the old cairn it was, I guess the word is replacing, the way a new fence post stands next to the rotten one. The old cairn was still there, gray-green with lichen, half its stones sloughed. The new one was clean. Clean the way a scrubbed incision is clean. And the base stones were dark at the ground line. I touched them this time, all of them, I made a point of it. Damp. Nine days no rain.

I stood there and did the reasonable thing, which was to be annoyed. Trail crew, I thought. Somebody's rebuilding the route markers. The Forest Service, a conservation corps, some Eagle Scout project with unusually good rockwork. I actually felt the annoyance resolve into that explanation with a little click, and I walked on, and the next new cairn came up, and the next, and somewhere around the fourth or fifth one the annoyance stopped resolving, and I stopped, and I want to try to describe the exact mechanics of what I noticed, because this is the center of the whole account and I've never once told it out loud without watching the listener's face do a thing.

The spacing was wrong. Not wrong like irregular. Wrong like regular. Each new cairn stood exactly at the limit of sight from the last one.

The terrain decides. Old cairns cluster where the route is confusing and thin out where it's obvious, they bunch at water crossings and junctions and vanish for a quarter mile where a shelf funnels you anyway, and their spacing is a fossil record of a hundred years of people getting briefly lost in the same six places. The old line, the lichened line, did exactly that. And threaded through it, six feet to the side, was the new line, and the new line had no relationship to the terrain at all. Whatever the ground did, whatever bench or dip or rise came, the next new cairn sat precisely where the last one stopped being visible. Never two in sight at once. Never a gap where you had to hunt. I tested it for most of a mile, I stood at a new cairn and found the next one right at the edge of seeing, a pale nipple of stacked rock at the exact range where detail dissolves, and then I walked backward away from a cairn, watching over my shoulder, and its next partner rose into view behind me at the moment the first one sank. Like they were counterweighted.

And on the rock at 1030, or 1040, somewhere in there, I had the thought that I have not been able to un-have since, the thought that made me sit down.

Spacing like that is not a property of the terrain. It's a property of the observer. The terrain doesn't know what I can see. Something had walked this line and stopped, each time, at the point where a person of about my height, with about my eyes, standing where I would stand, loses sight of the last marker, and had built there. The cairn line wasn't describing the route. It was describing me, or someone shaped like me, moving through. It was fitted to a body. And it had been built, the wet bases said, within the last day or two, meaning either just ahead of me, or just behind me, on the exact section of my exact route, in the exact window I was walking it.

I sat on the rock for a while. I don't know how long, I didn't write that down, which tells you something, because I write everything down.

Here's what I did next, and this is where the ER brain either saves you or embarrasses you, sometimes both. I triaged it. Out loud, actually, which is a habit from running codes, you narrate so the room stays organized, except the room was a thousand acres of granite and the room did not care. Airway breathing circulation, meaning, in this translation: am I in danger right now, is anything actually approaching me, do I have what I need. No, no, yes. Then differential diagnosis, most likely first, because when you hear hoofbeats you think horses. One: trail crew with a foreman who likes uniform spacing. Testable, sort of. Crews leave sign, boot tracks, tool marks, a spike camp, drill scars, and I had seen none, and a crew rebuilding two miles of cairns is six people and a mule string, not a ghost. Also crews don't build at the limit of sight, they build for bad weather, which means closer, denser, overlapping sight lines. I knew that from a volunteer weekend I did with a trail association in Colorado in 2017, we got a lecture about exactly this from a man named Dale with a clipboard. Intervisibility, Dale called it. You build for intervisibility in the worst conditions, not the best. Whoever built this line had built it for one specific set of eyes on one clear day.

Two: other hikers, the fast-and-light guys, someone playing a weird game. Possible. It's a free country and people are strange. But the rockwork was hours of labor. You don't gag-gift hours of moved stone to strangers you'll never see find it.

Three: I was wrong about the spacing, pattern-matching on noise, apophenia, the same wiring that makes people see rhythms in telemetry artifact. So I falsified it as best I could. I picked the next three new cairns in advance, predicted where each would appear based on nothing but my own sight line, said the prediction out loud, and walked. All three appeared where I said they would, at the range where my eyes run out. The old cairns, the lichened ones, failed the prediction constantly, they showed up close, far, doubled, absent. Only the new line tracked me. I wrote the test in the notebook that night, and reading it back now the handwriting in that entry is smaller than my normal hand, which is a thing my handwriting does that I hate.

Four: I did not have a four. Four was a shape with no name on it, and I left it blank the way you leave a line blank rather than write something you can't stand behind.

What I should have done at that point, per the route sheet, was consider my bail points, and I did, sitting on that rock with the map on my knees. Bail one was behind me: back over the saddle, past camp two, down the ramp, out Tepee Creek, sixteen and a half miles to the car. Bail two was ahead: finish the traverse, drop into Slide Creek, and the Slide Creek trail runs out to the same road at a different trailhead, seven miles of road walk back to the 4Runner, total maybe fifteen. So ahead and behind were roughly the same cost, and the country ahead was country I hadn't seen since 2019 and had paid for with four days of PTO and a five-hour drive, and the actual documented threat so far was: rocks, stacked. Write it that way and it's nothing. Rocks, stacked, recently, in a helpful line along a marked trail. Officers, he built navigational aids. The scariest sentence I could put in a report at that point was a sentence about masonry.

So I went on, and I'll tell you the truth, which is that going on felt fine for about an hour, because the new cairns stopped. Past the second lake the traverse rises onto a broad shoulder and the old lichened line carried on doing its old irregular thing and there was nothing new anywhere, and I ate lunch at 1215 by the outlet stream and the water was so cold it made the fillings in my teeth ring, and I remember thinking, there, done, whatever that was it's behind you, and Erin is going to love this story. The relief was real. I want to flag the relief, because relief is a symptom too. In the ED we have a saying, or Vic has a saying, about the patient who suddenly feels much better: sometimes better means better, and sometimes better is the lucid interval, and the whole trick of the shift is that they look identical from the doorway.

The second saddle went fine. Then the descent into the head of Slide Creek, and the smell.

The upper drainage of Slide Creek is a stepped gully, granite shelves with krummholz and little hanging meadows, and the trail switchbacks down through it next to the water. Approximately 1520, I dropped over a shelf into a pocket meadow maybe eighty yards long, still air, sun already off it, and walked into a smell so specific that my legs slowed before my head had processed anything. Sweet rot. And I don't mean generic bad smell, I mean the exact register of sweet that I know from work, the melena smell, digested blood, a GI bleed on contact precautions two rooms down, that dark sweetness with an edge under it that gets into the fabric of a shift. It's a smell I have a professional relationship with. My nose said room 14 and my eyes said alpine meadow and those two reports would not reconcile.

The obvious call is carcass. That's horses, not zebras, that country kills elk and deer all the time and a carcass in a still pocket of air will sit there smelling exactly like a Tuesday in the ED, and moreover a carcass means bears, which meant I made noise, got my spray on my chest strap where my hand knows it, and moved through slow with my eyes up. I never found the source, but I also didn't go looking under every krummholz mat for it, because you don't. I did find, and I photographed, a dead marmot on a slab well off the trail, dried out, weeks old, eyes gone, too old and too small to be the smell. The photo has a timestamp of 15:27. I mention the marmot mostly to show you I was looking, and that what I found didn't fit, which is the story of the whole trip in one sentence.

Here's the part I've never been able to file. As I climbed out the far side of that pocket, the sweet rot cut off, not faded, cut, like walking out of a room, and for maybe five steps the air was scrubbed granite nothing, and then there was ozone. That sharp bleachy electric smell. And my ER brain, which had just finished shouting GI bleed, said, without being asked: cautery. Bovie smoke, the smell when they cauterize a vessel, that mix of ozone and singe from an operating room or a bedside procedure. Blue sky. No storm within two hundred miles per the forecast, no storm anywhere I could see, and September's too late for that country's monsoon anyway. Dry air, dead calm, and a ribbon of ozone across the trail maybe ten feet wide, and then nothing again.

Ozone happens. UV, waterfalls, certain rocks after fracture, I've read genuinely stupid amounts of atmospheric chemistry for a nurse. Freshly broken granite can smell burnt, ask anyone who's drilled it. Maybe rockfall upslope had cracked something. That's my best offer. But smells in sequence like that, rot then clean then burn, in still air, in bands with edges, that's not how smell works outdoors. Outdoors smell smears. This was organized. It was like walking past rooms.

I made camp three at 1655 at the top of the big meadow on Slide Creek, planned camp, on my sheet, and here is where I have to chart my own vitals honestly: I was rattled in a way I hadn't admitted to myself, and I know I was rattled because of what I did with the tent. I moved it twice. First pitch was textbook, flat bench, water close, and I stood back and looked at the sight lines and moved it, tighter to the trees, and then I moved it again so the door faced the meadow, and I have been pitching tents for nine years and I do not move a pitched tent twice, and the third pitch had worse ground than the first. That's the chart. Behavior precedes insight. My hands knew before I did.

The hang that night went into a big Engelmann on the meadow edge, maybe eighty yards from the tent. I did the full system. I remember snugging my two ugly half hitches with the little twist and thinking, briefly, of Dale and his clipboard, and being comforted by the dumb human lineage of it, knots you learn from people who learned them from people.
