The Douglas Glacier is a glacier in New Zealand's Southern Alps located between Mount Sefton and Mount Brunner. It is named after the explorer Charles Edward Douglas.[1]
The glacier sits in a valley and is fed by several streams and frequent avalanches which drop down a cliff face of over 1,000 feet from its névé to the north.[2] The glacier itself was approximately 5 miles long in 1908.[2] The glacier has a relatively high rate of moraine materials, consisting of "friable phyllites and schistose grauwackes".[2]
At the foot of the glacier is a lake that was created by glacier recession.[3] Reports from 1892 and 1934 indicated it had "an anomalously slow lake development".[4] The Douglas River (formerly known as the Twain) begins in the lake at the foot of the glacier.[2]
