Woof’s favorite find
School Section Mine
We picked it because its USGS record mentions 5 gem or collectible minerals (Beryl, Tourmaline, Quartz, Garnet, Silver) and 8 of our card minerals overall. No other named site here scores as high on both counts. USGS lists it as producer for Mica, Beryllium, Feldspar. Minerals mentioned: Beryl, Tourmaline, Quartz, Garnet, Mica, Feldspar, Copper, Silver. Approx. location 38.472, -105.344. USGS record.
Ask first: a USGS record doesn’t mean you can visit. Find out who owns the land and get permission before collecting.

Produced ore or material at some point in the past.
The mineral was noted here, without development.

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 USGS ceased systematic updates to MRDS around 2011, so status and details may be out of date.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.
