Pumice Desert – Prominent Geological Features of Crater Lake National Park
#24 on the map – north side of Crater Lake
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.
