Sources & attribution
Everything on this site comes from somewhere, and every figure on every page names its source and the date it was last confirmed. This page lists those sources in full, along with the licence each is published under.
OpenStreetMap
© OpenStreetMap contributors
Map and location data from OpenStreetMap, licensed under the Open Database License (ODbL) 1.0.
OpenStreetMap is maintained by volunteers, many of whom map the dump station they use themselves. It is the best record that exists of standalone facilities — the ones at a highway rest area or behind a fuel station, which no federal database catalogues.
Recreation.gov (RIDB)
Data courtesy of Recreation.gov
Federal recreation data from the Recreation Information Database, published by the US government as a public domain work. It covers campgrounds operated by the Army Corps of Engineers, the Forest Service, the National Park Service and other federal agencies, and is the source for most facility detail here — hookups, site counts, maximum vehicle lengths, and photographs.
Photographs
Each photograph carries its own credit and licence beneath it. Where a picture shows somewhere *near* a location rather than the location itself, it says so. We would rather show you nothing than imply a dump station looks like a lake.
Contributions from travellers
Reports submitted by people who have been to a site become part of this data, credited to the display name the contributor chose. They are the most valuable records here — a federal database can tell you a dump station was built, but only somebody standing at it can tell you it works today.
Corrections
If something is wrong, tell us: <[email protected]>. Corrections are the point. A directory that cannot be corrected becomes wrong slowly and invisibly.
Reusing this data
The data on this site is a mixture of sources under different licences. The OpenStreetMap-derived portion carries ODbL's share-alike obligation and cannot simply be lifted into a closed database. If you want to build on any of this, write to the address above and we will tell you honestly what is reusable and under what terms.
