Lava Tongue Pass

Lava Tongue Pass (78°14′S 162°41′E) is a prominent north–south gully at 1,850 metres (6,070 ft) bisecting Radian Ridge in the Royal Society Range, Victoria Land, Antarctica. It was named descriptively by the New Zealand Geographic Board in 1994, following work in the area by a New Zealand Geological Survey field party, 1977–78, for a lava flow that fills the pass.
