Background
Double Glacier volcano is a Pleistocene lava dome complex forming a nunatak in Double Glacier. Potassium-Argon dates range from 627 to 887 thousand years ago (Reed et al. 1992). Nearby Double Peak, 5 km to the north, was once thought to be a volcano (Coats 1950, IAVCEI 1973), but reconnaissance mapping indicates the peak probably consists of Jurassic plutonic rocks (Reed et al. 1992).---
