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.

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 — Lantis Spring · Custer Gallatin National Forest · MT
- Surface water mapped nearby: USGS maps North Fork Plum Creek as an intermittent stream, ~0.5 mi from the pin (National Hydrography Dataset, data refreshed October 2022). Mapped as intermittent — expect it dry for part of the year. Nobody has checked it for you. Filter or boil anything you drink.
- Ground slope around the pin: about 12.8% — 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.
- The game's day in this forest These lines are for the whole Custer Gallatin National Forest, not for this camp's own spot: a fire restriction is posted by county, and a forecast is for one point in the forest. A camp's own night can differ from that point, most in the mountains. Read when this page loads from the same daily files the game uses; every line says where it came from and when it was read.
- This camp's own spot: sun and fire record Worked out for this camp's recorded point from federal records, not for the whole forest. Every line says where it came from and when.
Sun behind the west ridge: (USGS 3DEP elevation, bare ground, 30-meter steps, finer close to camp; trees not counted; worked out October 15, 2026 for the 15th of each month, in this forest's clock; nobody has stood on it for this.)
Fire history: Inside the 2002 Kraft Springs fire perimeter (85,186 acres), by the national fire history record. Inside the 1988 Brewer fire perimeter (52,561 acres), by the national fire history record. (NIFC InterAgency Fire Perimeter History, read October 15, 2026. This says where the record draws the line at this camp's recorded point, not what the ground here is like.)
- 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.

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
Free but developed (not dispersed) - review || Water: Custer Gallatin National Forest's own site page for Lantis Spring Campground, https://www.fs.usda.gov/r01/custergallatin/recreation/lantis-spring-campground (read 2026-08-13; page "Last updated" May 4, 2026), "Facility and Amenity Information > Water": "Potable water is not available at this site." plus "Spring has non-potable water.". Corroborated by the USFS EDW Recreation Sites layer (apps.fs.usda.gov/arcx/rest/services/EDW/EDW_RecInfraRecreationSites_02/MapServer/0, queried 2026-08-13), WATER_AVAILABILITY = "Water can be treated or filtered from nearby water sources". Both channels agree; nightshift fire 610.

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 Lantis Spring
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.
- Whether that MVUM road is the way in, and the last stretch beyond it
- Whether the site itself closes on its own schedule — only the road's season is on record
- How many rigs actually fit
- Cell coverage by carrier
- 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
