Last Day at Yellowstone

 We took sometime to see more of the caldera area at Yellowstone, along US-191. Old Faithful is only one of many geysers, mud pots and steam vents. The  Yellowstone supervolcano last erupted about 640,000 years ago. When it did, it left behind a caldera, a landform created by the inward collapse of a volcano's peak. These links will explain it. Our next stop will be Salt Lake City, Utah.

Scenery is great, ranging from mountains, canyons and open land.

The next photos are from the Firehole Lake area, a short drive east of US-191.
The Firehole River follows US-191 on the west side of the highway.

The red stains are from algae that lives in the hot water.

Boiling water.

Calcium carbonate covers the ground around the vents.

A lot of calcium carbonate. We just missed the eruption here.

More boiling water.

There are several water falls in Yellowstone.
