That's a great idea for immersion, too: Field trip guidebooks! Most states have non-governmental associations of geologists, most of which are academics but in high activity areas for oil and gas and mining, often including industry geologists, too. Back East, the Carolina Geological Society (CGS) meets annually for a 2 day bus borne field trip. Surely other state societies do so also. I recently "discovered" the fine work of "Friends of the Pleistocene" in Nevada and California, which points to opportunities for field trips and related guidebooks from other types of organizations also.
Hmmmm, I've got 2 days in Elko this summer, one being to see the big Silver State Stampede rodeo. Might need to run down to the Rubies and bomb around in the truck the next day before heading out to Jarbidge.
