Lamplugh Glacier is an 8-mile-long glacier located in Glacier Bay National Park and Preserve in Alaska. It leads north to its 1961 terminus in Johns Hopkins Inlet, 1.4 miles west of Ptarmigan Creek and 76 miles northwest of Hoonah. The glacier was named by Lawrence Martin of the U.S. Geological Survey around 1912 for English geologist George William Lamplugh (1859–1926), who visited Glacier Bay in 1884.
Lamplugh Glacier is roughly 160 feet high at the face, and about 3/4 mile wide. This tidewater glacier has advanced and receded significantly in the past century.
The black/brown staining that you can see on the glacier is actually sediment and rock that is ground to a fine powdery dirt. This is caused by the glacier's slow movement from the background to the foreground, before calving/falling into the Bay.
