Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Topaz Mountain in Juab County’s Thomas Range is Utah’s classic free-collecting topaz ground. Wind and weather free sherry-to-clear topaz crystals from rhyolite; red beryl and garnet turn up for careful eyes. BLM public land—hand tools only, fill holes, and avoid patented claims. High-clearance dirt roads; brutal summer heat.
