Pumice Desert - Prominent Geological Features of Crater Lake National Park
The Pumice Desert is a broad flat in the northern section of
the park. This desert was covered with pumice and ash more than 200 feet
deep in some places by the explosion of Mount Mazama. It has only started to
be invaded by scattered lodgepole pines. Due to its scarcity of organic
matter, few plants have taken hold to further enrich the soil.
