Mosley-Thompson Cirques
The Mosley-Thompson Cirques () are prominent steep-walled a cirques that indent the western part of Colwell Massif, Victoria Land, Antarctica. They were named by the Advisory Committee on Antarctic Names in 1994 after glaciologist Ellen Stone Mosley-Thompson of the Byrd Polar Research Center, Ohio State University, who for many years from 1974 onwards analyzed ice samples from Antarctica and conducted field research at the South Pole, at Siple Station, and at Plateau Remote Camp.
130 million years ago when the microcontinent collided with the much larger North American continent. The process uplifted the complex and exotic terranes of the microcontinent to form the Klamath Mountains. Many glaciers carved U-shaped valleys and cirques during the last ice age, and several alpine lakes still exist today.
Today, sandstone, shale, granite, and serpentine are the primary rock types in the Chetco region. Various forms of loam comprise its soil. Erosion levels are high due to a combination of high precipitation, steep slopes
