Eden Valley — Rockhounding in Sweetwater County, Wyoming

Eden Valley is the Wyoming benchmark for silicified and agatized wood, with Mindat records tying petrified wood to Eden Valley and the Blue Forest area. It also has unusually clear legal framing, since BLM specifically allows limited personal-use petrified wood collecting on open public land while keeping fossil and commercial-use rules separate. Reported finds include silicified wood. Below: coordinates, access notes, nearby spots, and trip-planning links.
