Mount Newton is part of the Saint Elias Mountains in Kluane National Park where it ranks as the 22nd-highest summit in Canada.

[6] The remote mountain is highly glaciated and surrounded by the Seward and Newton glaciers.

[1] Topographic relief is significant as the summit rises approximately 1,700 metres (5,577 ft) above the head of the Newton Glacier in 3 km (1.9 mi).

The mountain's toponym was officially adopted in 1917 by the Geographical Names Board of Canada to honor US geologist Henry Newton (1845–1877), grandson of Sir Isaac Newton and author of a report on the geology of the Black Hills that confirmed gold there.

[9] Weather systems coming off the Gulf of Alaska are forced upwards by the Saint Elias Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall.
