Sea-Floor Sunday #37: Crater Lake, Oregon

December 14, 2008

Okay … this is obviously not the sea floor … but Bathymetry Image Sunday just doesn’t have the same ring to it.

This week’s image is courtesy of the USGS and is a perspective image of Crater Lake  in Oregon.

This image is from this USGS site — here’s a blurb about Crater Lake.

Crater Lake, the deepest lake in the United States, occupies a caldera in Mount Mazama, a Cascade Range volcano that once stood about 3,700 meters (12,000 feet) above sea level. About 7,700 years ago in a catastrophic eruption that lasted only a few days, Mount Mazama ejected about 50 cubic kilometers (12 cubic miles) of magma in the form of pumice and ash. Near the end of the eruption, the mountain collapsed upon itself to form a large caldera. After this climactic event, volcanic activity resumed within the caldera, creating Wizard Island and other new landforms. All but the uppermost portion of the Wizard Island volcano is hidden from view below the surface of Crater Lake.
