Ask about this camp →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.

- Power (kW)not listed by AFDC — “DC fast” spans roughly 24 to 350 kW, so ask the network.
- Read this honestlyStraight-line miles, like every distance on this site. Roads run longer than this, and you have to get back. We know where a charger is listed. We don’t know if it works today, how fast it is, or the road miles. Check the network before you commit.

The unit that manages Avalanche20
Stay limits, road closures and fire restrictions at Avalanche20 are set by Helena-Lewis and Clark National Forest, not by the campsite — check there before you go.
Snow, and when this opens
The nearest automatic snow station is Pickfoot Creek at 6,680 ft, about 14 miles away. It sits about 1,783 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.

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).
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 Avalanche20
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.
- Road surface & last-mile access
- How many rigs actually fit
- Cell coverage by carrier
- Seasonal & winter access
- Current fire restrictions
- Whether any water here is drinkable
- Shade & wind exposure
- Noise and who else shows up
- Whether a listed EV charger works today, or the road miles to it
