Scientists have completed their mission to map one of the most extraordinary mountain ranges on Earth.

The Gamburtsevs are a set of peaks equal in size to the European Alps, but they are hidden deep under the ice in the middle of the Antarctic continent. [...]

EXPLORING THE SUBGLACIAL GAMBURTSEV MOUNTAINS

1. Aircraft used radar to detect ice thickness and layering, and mapped the shape of the deeply buried bedrock

2. The planes also conducted gravity and magnetic surveys to glean more information about the mountains' structure

3. By listening to seismic waves passing through the range, scientists could probe rock properties deep in the Earth
