Check access before you go. Most sites listed here are old mines, quarries or prospects, and many are on private land or active mining claims. Get the landowner's permission, check the rules of the agency that manages any public land, and never enter mine workings. Locations are approximate.

Woof’s favorite find

Grand Bay Quarry

We picked it because its USGS record mentions 1 gem or collectible mineral (Quartz) and 1 of our card minerals overall. That ties with 4 other site(s), so we broke the tie by mine status (past producers first), then USGS record quality, then name. USGS lists it as producer for Silica. Minerals mentioned: Quartz. Approx. location 30.529, -88.292. USGS record.

Ask first: a USGS record doesn’t mean you can visit. Find out who owns the land and get permission before collecting.

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 USGS ceased systematic updates to MRDS around 2011, so status and details may be out of date.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