Ask an AI about this campsiteOpens Grok already loaded with this site. It reads the same records this page is built from, and links whatever it tells you.
Ask about this camp →U.S. Forest Service lists this as a developed campground. Expect marked sites, a fee station or a reservation, and the usual campground rules. The dispersed-camping freedom of the surrounding forest does not apply inside it. What changes is conditions — roads, gates, closures, fire rules. Check those with the unit before you commit to the drive.
Nearest road on the Forest Service MVUM — Halfmoon · Custer Gallatin National Forest · MT
No MVUM road within 1 mi of the pin; access may be a county road or unmapped.
From the Forest Service's own Motor Vehicle Use Map roads layer (EDW, Clearinghouse refresh Aug 30, 2026), straight-line from the pin to the nearest mapped segment. The nearest segment is not necessarily the way in, a maintenance level is the agency's class and not a report on today, and a road's season is the road's — it is not a campground order.

Coming out here — Halfmoon · Custer Gallatin National Forest · MT
- Surface water mapped nearby: USGS maps Big Timber Creek as a perennial stream, ~0.1 mi from the pin (National Hydrography Dataset, data refreshed October 2022). Mapped as perennial is not the same as flowing today. Nobody has checked it for you. Filter or boil anything you drink.
- Ground slope around the pin: about 9.7% — noticeable. Measured on USGS's 3DEP elevation model (1 m data here), sampled every 10 metres around the point. That is the hillside, not the ground under your wheels — a graded pullout or a bench a few metres across is too small to show up at that spacing, and nobody has checked this one for you.
- No rail line and no interstate or US route is mapped within 10 mi of the pin. Checked against the FRA/BTS North American Rail Network (data updated Jul 21, 2026) and the Census's TIGER/Line primary roads (TIGER/Line 2025, released Oct 2025). Both are national files and both are maps of what is built, not counts of what moves on it.
- 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 — Starlink pays Dave $100 in cash if you sign up through it, and that money funds this site and the next trip. It costs you nothing and does not change the recommendation.

The unit that manages Halfmoon
Stay limits, road closures and fire restrictions at Halfmoon 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 S Fork Shields at 8,090 ft, about 10 miles away. It sits about 1,639 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.

Likely — The record is good enough to put a pin on, but thin in places. Treat the details as a starting point, not gospel.

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 Halfmoon
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
