Woof’s favorite find
Western Uinta Range Group
We picked it because its USGS record mentions 3 gem or collectible minerals (Tourmaline, Quartz, Fluorite) and 5 of our card minerals overall. No other named site here scores as high on both counts. USGS lists it as prospect for Phosphorus-Phosphates. Minerals mentioned: Tourmaline, Quartz, Feldspar, Pyrite, Fluorite. Approx. location 40.517, -111.101. USGS record.
Ask first: a USGS record doesn’t mean you can visit. Find out who owns the land and get permission before collecting.
Field cards: what kind of sites?
The mineral was noted here, without development.
Produced ore or material at some point in the past.
Was producing when the record was made.
Explored or test-dug, with no recorded production.
Status terms come from USGS MRDS records.

How we built this page: we counted named sites in the USGS Mineral Resources Data System (MRDS) for this area, left out sand, gravel, crushed stone, clay pits and unnamed sites, grouped them by Census county, and linked every site to its USGS record. We did not visit these sites, and MRDS does not tell you who owns the land or whether collecting is allowed.
Source: USGS Mineral Resources Data System (MRDS). USGS ceased systematic updates to MRDS around 2011, so status and details may be out of date. Each site links to its USGS record.
