U.S. Forest Service lists this site. On most of their ground you can camp away from developed sites pretty much anywhere — so treat this as a known-good spot, not the only one allowed. The unit sets stay limits and how far off road and water you must be. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.

Snow, and when this opens

The nearest automatic snow station is Twelvemile Creek at 5,530 ft, about 10 miles away. It sits about 1,378 ft higher than this camp, so treat it as a guide rather than a reading for this spot. We do not repeat a depth here, because any number we stored would be stale by the time you read it — the station publishes today's.

How we know this — Lost Horse 015B

Source
U.S. Forest Service recreation data
Confidence
Likely — The record is good enough to put a pin on, but thin in places. Treat the details as a starting point, not gospel.
How it was placed
USFS/BLM authoritative: free & dispersed. Access not field-checked (assumed drive-up).
Nearest MVUM road
US Forest Service Motor Vehicle Use Map roads layer (EDW_MVUM_01, layer 1), Clearinghouse refresh Aug 30, 2026. Straight-line distance from the pin to the nearest mapped segment within 1 mi; surface type, maintenance level and open dates are the agency's own values for that segment, expanded from its codes and otherwise unedited. Nothing here says which road reaches the site.
EV chargers
US DOE Alternative Fuels Data Center station locator, snapshot 2026-09-16. Straight-line miles to the nearest public, open, unrestricted station; restricted and planned units are shown but never counted.
Field check
On the agency's books. The land manager inventoried this site, so its existence is not in question — current conditions are. Nobody from here has camped it recently.

What we don’t know about Lost Horse 015B

A land record can put you within a few meters of a spot. It cannot tell you any of this — so check it yourself, and treat anything below as the open question it is.

Is this page wrong about Lost Horse 015B?

This page was built from a public land record, not from a visit. If you have actually pulled in here and it does not match, that is worth more than anything we can read off a map. Tell Dave what is off — it goes to him, not onto the page.

What did you find? Tick anything that fits.

A reader report is not a fact, and this one will not change a word of this page by itself. Dave reads it and checks it against the agency’s own record, because that record is what this site says. If reader reports are ever shown here they are labelled “reader report, unverified” with the date, and they are never merged into the agency fields.
