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]

Potassium-argon dating has indicated ages of 1.4-0.9 mya.[1] The cone is constructed from basalt and hawaiite including lava bombs in its sides.[2] Similar to Seal Nunataks and James Ross Island the rocks of Argo Point are ocean island basalts. This volcanism may be the consequence of back-arc effects of subduction along the South Shetland trench.[4]
