Bay Area Collectors
The Bay Area is one of the "hotbeds" for mineral collecting in the US, with many of the nation's pre-eminent collectors located in the area or nearby. Here are websites DriftMine has come across which feature these collections, and offer some entertaining browsing.
1. The Saint Marie Aux Mines "Best of Collectors" (several of whom hail from the Bay Area and other parts of California).
2. The Richard Geiger collection (a personal website with innovative search features).
3. Some pictures of minerals in Steve Smale's collection (his website).
