Welcome to The Black Hills
It was shut down for some time years ago from stupidity. People trashed it and graffiti some of it. So, let's keep this awesome piece of the American West open for generations to come by using common since, hiking out what you hike out, and not demolishing the history and local wildlife (the bats).
I saved the best for last so stay with me till the end.
This is the Ingersoll Mine itself. As old and crumbly as the structure is, it is still well enough intact to explore at your own risk. Of course you have to check out the old thing, who wouldn't ;)
I really like the below picture where you can see the old chutes. It is easy to imagine the sorting process.
Hiking farther up the mountain, we came to this huge mine. This particular one was real neat. The rock was so solid that there was minimal supports along the way. It appeared to me that this mine might be more resent than the last one I will show you, but I could be wrong. None the less, the Ingersoll Mine was proving to be worth the hike. This mine was not super long but very intricate and real pretty.
Down the trail and onto the big guy! This mine was so cool and took up most of our day. This is the stuff America was built upon, ingenuity and hard work. It is so crazy to think how these guys were able to do all of this.
