Yellowstone, 9/18

Firehole Canyon Falls

The entrance to Firehole Canyon. There is a swimming hole in the canyon; it is the only legal place to take a dip in Yellowstone. Despite the chilly temperatures (about 55 degrees), we did see a kid skinny-dipping. The water temperature in the river is higher than normal because of all of the heated springs that empty into it.

This is the north rim of the Yellowstone Caldera (in case you don't know, Yellowstone sits on the most active volcanic hotspot in North America) near Madison Junction.
