Dugway Range: Beryl & Chalcedony Rockhounding in Juab County, Utah

Updated June 2026

The Dugway Geode Beds are one of Utah's clearest geology-to-specimen localities: Miocene rhyolite cavities were eroded by Lake Bonneville and redeposited as diggable geodes in lake sediments. BLM lists the beds as a rockhounding hotspot, and UGS notes that the geodes commonly contain clear, purple, or pink quartz. Reported finds include beryl, chalcedony, fluorite, garnet, topaz. Below: coordinates, access notes, nearby spots, and trip-planning links.
