Animal jams as we entered the park – elk grazed along the Madison River and had a large audience jockeying for photos.
Firehole Canyon rewarded us with many surprises. The Firehole Falls was a lovely stop, the water, trees and sounds of the falls. Up the river a bit, was a gaggle of swimmers who were enjoying the water. They must have found a warm spot!
There is a great museum near Old Faithful that explains the geothermal features of the park as they relate to volcanism. The central section of the park is in a collapsed volcanic caldera. Heat from the magma chamber is what fuels the geysers and other features.
