The Pumice Desert of Crater Lake

POST #    2230

One of the first things visitors that enter through Crater Lake's North Entrance see is the Pumice Desert. The desert is about 5.5 square miles and covered with material that was created when Mount Mazama exploded. Mazama no longer exists, but its explosion was one of the events that created Crater Lake. Some of the ash, pumice and other material that flowed out of Mazama settled in the valley was once where the Pumice Desert is now. The deposits reach over 100 ft in some areas and is has a very small amount of plant life on it compared to the surrounding area.

As you can see, there is lots of haze in the pictures above (like yesterday, click to enlarge) due to a wildfire nearby. More on that fire at some other point.
