Background
A large number of isolated basaltic scoria cones are located throughout Antarctica's northern Victoria Land near the western coast of the Ross Sea, not clearly associated with the larger stratovolcanoes. One lava flow on the southern side of Cosmonaut Glacier, SW of Mount Overlord, spilled onto the glacier and diverted it, but has not yet been removed by erosion or covered by ice. Nathan and Schulte (1968) inferred a possible age for the lava flow of less than a thousand years, but not greater than 50 ka. Potassium-Argon dates from Overlord (see separate volcano entry) indicate an age of about 7 million years ago (Kyle 1977, pers. comm., LeMasurier and Thomson 1990). There is no clear evidence of Holocene activity from any of these poorly-studied basaltic rocks, called the "Local Suite" by Nathan and Shulte (1968).---
