|Not just any old hillside|
It may look like any old hillside, but this one is quite remarkable.
This particular hillside just happens to be along part of the fault zone created when the roof of the Yellowstone caldera collapsed into the magma chamber following the colossal volcanic eruption around 640,000 years ago. It is one of the few places in the entire park where the fault zone is easily visible and unmistakable, once you know it is there.
