Montezuma County, Colorado · Game Management Unit 711
A high-desert mule deer and elk preserve on the Great Sage Plain — held under one ownership, managed against evidence, and documented animal by animal.
01 — The Ground
The ranch sits on the Great Sage Plain northwest of Dolores, a high tableland of sagebrush, piñon and juniper broken by dryland farm ground and cut by shallow draws. It runs two and a quarter miles north to south and falls four hundred and thirty-nine feet across that distance, which is why the deer move the way they do and why the elk come down when they come down.
Four sections, twenty-eight forty-acre aliquot parts, one contiguous block, one ownership. There is no adjoining lease, no shared access and no second party with a say in how it is run. That is rarer in this country than the acreage is.
In high desert water is the whole story — of where the animals are, of what the ground can carry, and of what a manager can change. Which draws hold it, which of them are still holding it in August, and what moves when you add one: those are the first questions the record is being built to answer, and they are questions this country has never had a straight answer to.
The resident herd, and the animal the place is managed for. Piñon-juniper edge, sage flats and the draws between them.
Seasonal, and the arrival date is one of the things now being measured rather than remembered.
Along the timbered edges and the water.
Black bear, mountain lion, coyote, bobcat, and the raptor and small-mammal layer that tells you whether the habitat work is landing.
02 — Method
Every property in this business calls itself managed. Most of the time that means somebody puts out feed and has an opinion about which bucks to leave alone.
What is being built here is different in one specific way: it produces evidence. A camera and sensor network across the whole property, every animal identified and classified, every individual buck and bull given a file that follows him for his whole life, and every habitat decision measured against the part of the ranch where nothing was changed.
The point is not the cameras. The point is that a question like did the new water actually move anything stops being a matter of opinion.
03 — The Line
Colorado's wildlife regulations prohibit using a live-transmitting camera to locate or surveil game for taking during the same or the following day. 2 CCR 406-0, Regulation #004(E).
A great many operations would treat that as a policy line in a document nobody reads. Here it is written into the software at the layer every request has to pass through. During any open season, for anyone holding a license for that species, a live frame and a camera control return a refusal — and the refusal is logged.
We would rather the machine be incapable of it than trusted not to. If you are looking for a place that will show you where the animal is standing this morning, this is not that place, and it never will be.
Population, condition, range use, corridors, water. Open to everyone, all year.
Seven miles of boundary, and a way to know that a guest alone out there is alright.
Thermal picks up smoke on a piñon-juniper property at 7,000 feet before anyone smells it.
Structurally impossible during season. Not discouraged — refused, at the API, with an audit trail.
04 — The Record
Most places sell a claim about big deer. What this one can offer instead is the documentary record of a specific animal's life — first seen as a yearling, every year of antler growth drawn to measurement, his core range mapped, the does he ran with, and the four autumns he spent on this ground before anyone laid eyes on him in person.
Nobody else in this county can produce that, because producing it requires owning the ground the animal lived on and watching it for years before it mattered. It is the reason to start now rather than in the spring, and the reason a landowner voucher from here is not the same instrument as a landowner voucher from anywhere else.
Where he was born to the extent it can be known, where he lived, and where he was when.
Antler measurements year over year, and what the range was doing in each of those years.
Observed rather than estimated, because the register watched him become what he is.
Score and age confirmed after the fact and fed back, so the record corrects itself rather than hardening.
05 — Open Now
Fifty-five photographs of wild mule deer and bull elk, live today. You call the score, the age and the weight. Then the sealed call comes out of the envelope — written before the page went up, with the reasoning behind it — and you get to say why it is wrong.
There is no answer key. Nobody put a tape on these animals, so the machine is guessing from the same picture you are, and its distance from the people who know is its error, not theirs. It keeps that score on itself in the open.
Play the Windmill EyeIndividual scores in that study ran from 16% to 56%, and accuracy fell as the deer got older — which is exactly backwards from where the decisions matter. Meanwhile a modest computer-vision model reached 77% cross-validated on fewer than two hundred labeled photographs.
Both halves of that are the argument for this exercise. Human judgment on a photograph is far less reliable than the people making it believe — and it can be corrected, once it is measured. That is what the Eye measures, and it is what the register will be built on.
06 — The Country
Twenty-odd miles northwest of Cortez, on the road between Lewis and Dove Creek. This is the corner of Colorado where the Colorado Plateau starts — mesa tops, canyon heads draining south toward McElmo and north toward the Dolores River, and some of the highest density of archaeological sites anywhere in the United States.
Canyons of the Ancients National Monument is the neighbor. Mesa Verde is forty minutes. The San Juans stand up on the eastern skyline. It is quiet, it is high, and there is a great deal of country in every direction.
25 minutes · groceries, fuel, a regional airport with commercial service.
1 hour 15 · the nearest city, and the nearest jet service.
40 minutes · and Canyons of the Ancients begins at the fence line country.
7,000 to 7,500 feet · cold, dry, and a very long way from a city light.
