Bone Basin Perry Cyn-071

Coming out here — Bone Basin Perry Cyn-071 · Beaverhead-Deerlodge National Forest · MT

• No named surface water mapped within 1 mi of the pin in USGS's National Hydrography Dataset (data refreshed October 2022), and none within about a mile and a half in our OpenStreetMap pull — which is not proof there is none, only that neither map has one. Plan to carry washing water as well as drinking water.
• Ground slope around the pin: about 10.6% — 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.
• 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.
• Rail line mapped ~4.6 mi from the pin — the national rail atlas classes it as an industrial lead. No track the atlas classes as a main line is mapped within 10 mi. That is the FRA/BTS North American Rail Network (data updated Jul 21, 2026), which records that a line is there and what class of track it is. Whether anything runs on it, how often, and at what hour, it does not say, and nobody has checked this one for you.
• Interstate 90 is mapped ~9.1 mi from the pin. Straight-line, from the Census's TIGER/Line primary roads (TIGER/Line 2025, released Oct 2025) — the divided, limited-access highways, which is why a state expressway or a two-lane US route near this camp would not appear here.
• 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 — 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.
