Travel photo of the week: Aug. 11, 2006's Bill Geer took this beautiful picture of Crater Lake while on vacation in Oregon in June.

This feature was created about 7,000 years ago when an active volcano finished a major eruption. The magma chamber below the mountain was emptied by the eruption and the mountain collapsed into itself. The cauldron filled with water over the centuries and subsequent eruptions formed several cinder cones within the cauldron - one of which is visible today above the water's surface. This area receives some of the heaviest snow fall for the region and averages about 533 inches per year. (Bill Geer /
