History of Main Valley

Named in 1882 by John Muir when the valley was occupied by a branch of Muir Glacier. In 1890 H. F. Reid (1892, pl. 114), U.S. Geological Survey (USGS), showed Main Valley as the icefilled portion NW of Main Lake. Later Reid (1896, pl. 86 and 90), named the entire valley Endicott Valley because it drained into the Endicott River. With the retreat of the Muir Glacier after 1890, the entire valley was uncovered. The northern part of the valley now drains into Muir Inlet, and the southern part drains into the Endicott River.
