(Redirected from Mount Isbell)

The Geologists Range is a mountain range about 55 km (34 mi) long, standing between the heads of Lucy and Nimrod Glaciers in Antarctica. Seen by the northern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1961–62) and named to commemorate the work of geologists in Antarctic exploration.[1] The Churchill Mountains are to the north, the Queen Elizabeth Range to the east and the Miller Range to the southeast
