The Crater Lake Adventure
















Ever been to a caldera? Well, we have! The closest, and most scenic caldera to us is Crater Lake National Park. As our regular readers know we visited Crater Lake two weekends ago (remember this?). Here are some pictures of the Crater Lake area.

Some background... The caldera formed nearly 8,000 years ago when the volcano, Mount Mazama, erupted. The eruption emptied most of the magma chamber, which caused the great collapse forming the caldera. Centuries of rain and snow helped to fill in the caldera with water - forming Crater lake.
















To the north of Crater Lake is the Pumice Desert. Mount Mazama ejected hot ash over this area, probably killing all the indiganous life. Thousands of years later the area still as yet to fully recover. Most of the areas to the west and south of Crater Lake have fully restored pine forests, but not this area. Few trees and vegetation have returned.

The steep edges of the crater.




























In the background you can see Wizard Island. This cinder cone volcano formed after Mount Mazama blew and collapsed.





















Seven miles from the crater, these interesting formations were created. Volcanic vents formed in the ash deposits. The super-heated gas melted parts of the ash to form pillars. The rest of the ash was eroded away to leave these mostly hollow tubes.
















Native American tales tell of crayfish monsters grabbing gazers of the lake and pulling them in. We can see were the tale may have originated - one could get lost taking in the sites and inadvertently take one too many steps towards the lake. If you ever go, be careful of the edges.
