Tim, the Sonora area is very big on old mining history. However, the obscure places like Markleeville are nice also. Some places were big on gold, some were big on silver, and some were other. Some of the historic areas have restored the old mine cabins and mills. In other places, you have to know what was there 150 years ago to have any appreciation.
It is also fun to read up on the original pioneer routes into California. Of course that was back in the days of horses and mules. Now, a few high-speed highways follow the same routes, more or less. So, as you drive along and stare out the windshield of a car, you can think back to the miner on his horse and what it must have seemed like back then.
There was very little mining that happened within what we now call Yosemite National Park, but there was some on borders and just outside the park in each direction.
