Phone before you drive

recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.

Booking window6 months outBooking opens 6 months ahead; today unlocks arrivals through April 16, 2027. The agency publishes no reservable season in the record we hold, so the window may close earlier than that.recreation.gov

Derived by CAMPANAC: the lowest per-night amount the agency’s fee record states ($10), and no booking fee, because this campground takes no reservations. A weekend here means Friday and Saturday night. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.

How we know

every fact on this page, and where it came from
Right now: U.S. Forest Service publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate.
Elevation: USGS 3DEP elevation point query at this campground’s coordinate · Sep 7, 2026
Night sky: VIIRS Day/Night Band annual cloud-free composite, VNL V2 2024 (Earth Observation Group, Colorado School of Mines), read at the published coordinate: 0.012 mcd/m² of artificial all-sky glow, ranked against the 501 rated federal campgrounds in Montana · Sep 8, 2026
Sky-glow model: Duriscoe, Anderson, Luginbuhl and Baugh (2018), a simplified model of all-sky artificial sky glow derived from VIIRS Day/Night band data, the National Park Service sky-glow model
Cell signal: the Forest Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
