I have a lot of interest in old mines. An amateur geologist, very amateur. I would to go thru old discarded rock piles, and take photos of old mines and homes. You can't help thinking of the miners, families, and others that lived and worked there.For me it would have been a hard but wonderful time to be alive. I think at one time I may have been a 49'er. I collect rocks and agates. Need to get a rock tumbler.
