Data sources

• Campsites and dump stations: OpenStreetMap, © OpenStreetMap contributors, licensed under the Open Database License. A campsite is listed as free when it is tagged with no fee.
• Nearest town: U.S. Census Bureau Gazetteer place file (public domain). Distance is straight-line, not by road.

Labels such as "RVs OK", "Toilets" or "Potable water" appear only when the source says so; a missing label means unknown, not absent. Fees, seasons and road conditions change — check with the managing agency before you travel. Spotted a closed or wrong listing? You can correct it directly on OpenStreetMap, and it will update here within a week.
