Argo Point (scoria cone)

Argo Point is a scoria cone in Jason Peninsula, Antarctica, at a height of 360 metres (1,180 ft) above sea level.

[1] Associated with the Seal Nunataks, the cone has a diameter of 300 metres (980 ft) and its snow-filled crater has a gap on its northern side.

The cone is constructed on a formation of lava and scoria over 175 metres (574 ft) thick, which may lie on Jurassic rocks.

[2][3] Glaciers or wind have eroded debris from the cone, forming a "tail" several kilometres long on the ice.

[4] The cone is constructed from basalt and hawaiite including lava bombs in its sides.
