There are lots of old mines of all types in these parts.
The farther south we rode the more desert-like became the terrain. And it was HOT!
There were sunflowers everywhere along the trail.
We were told this is an old uranium mine.
The ride ended in a park next to the real railroad in Edgemont. And, yes, it was hot!
The program for the evening was a very interesting talk by Jon Nelson, co-author of the book Crossing the Plains with Custer about researching Custer's Black Hills expedition.
