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 ($23), 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 this receipt · 6
Sign price: Derived by CAMPANAC from the U.S. Forest Service fee record: a stated per-night amount only · Sep 7, 2026
Booking fee, change fee, cancellation fee, no-show: Rules and Reservation Policies, Recreation.gov, the published fee schedule, curated by hand into lib/reservation-fee-schedule.json (9 rows, each carrying its own verbatim sentence). The publisher states these policies were last updated September 2019. · Sep 9, 2026
What this campground adds: The U.S. Forest Service’s own fee record and notices for this campground, quoted verbatim. An extra-vehicle charge is set locally and appears on no national schedule, so it’s never assumed. · Aug 24, 2026
The two totals: Derived by CAMPANAC by adding the agency’s own published nightly rate to recreation.gov’s own published reservation fee. Both components are cited above; the addition is ours and is shown only where every component is known. · Sep 9, 2026
Who keeps the booking fee: Recreation.gov facility policy text, Dead Swede Campground (facility 234221) · Not on the national policy page. This is agency policy text recreation.gov publishes on individual campground pages; this site holds it verbatim on 45 active campgrounds (campground_rules.cancellation_description, scripts/load-facility-rules.mjs). · Sep 9, 2026

How we know

every fact on this page, and where it came from
Right now: U.S. Forest Service’s own recreation database flags it not open and publishes no reason and no date. That’s a flag, not a notice.
Listed not open: USFS EDW Recreation Opportunities, openstatus field: a not-open flag in a database, with no reason and no date published; read there since Sep 9, 2026. A flag, not a notice, so this page doesn’t call it a closure. · Oct 17, 2026
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: 0.052 mcd/m² of artificial all-sky glow, ranked against the 248 rated federal campgrounds in Wyoming · 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.
