TerraDiscovery’s 50-State Rockhounding Map
A beta discovery database for finding places to look for fossils, gemstones, gold, relics, and other geological curiosities across the United States.
Field notes
The project organizes outdoor discovery sites by state and material, with separate controls for activities such as pay-to-dig, gold panning, fossils, meteorites, and metal detecting. Its current homepage reports 29 verified all-gems places and offers both map and list views, while the public-beta notice labels listings as demonstrations. Visitors are told to check each property’s current rules before making a trip, so the database is a planning aid rather than a substitute for local access research.
