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.

- 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.

Coming out here — S Rock 003 · Custer Gallatin National Forest · MT
- Surface water mapped nearby: Rock Creek (stream). That is wash water at best, and nobody has checked it for you — a creek can be dry and a tank can be mud. Filter or boil anything you drink.
- Assume no services at all. Most dispersed camping in a national forest has none: no tap, no power, no dump, often no toilet. Everything you need, you bring.
- Power: Dave carries his own — batteries or solar. A generator will run your rig and it is also the thing everybody camped near you can hear.
- Getting online: Dave recommends Starlink. He has had it since SpaceX introduced it, used it for four years living on the road, and it delivers as promised — several hundred nights out, and he can count on one hand the places he could not connect. The cable on his unit runs 150 feet, which is usually all it takes to find enough sky. Starlink → Referral link — Dave gets service credit if you sign up through it. It costs you nothing and does not change the recommendation.

The unit that manages S Rock 003
Stay limits, road closures and fire restrictions at S Rock 003 are set by Custer Gallatin National Forest, not by the campsite — check there before you go.
Snow, and when this opens
The nearest automatic snow station is Shower Falls at 8,060 ft, about 14 miles away. 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).

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 S Rock 003
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
