Volcanic Soils

The Grand Canyon of Yellowstone is about 24 miles long. In this area of Yellowstone the underlying rhyolite rock has been hydro-thermally altered, making it very soft, brittle, and it erodes easily. That's also why you have these gorgeous colors of reds, pinks, and browns in the photo.
