DESCRIPTION
This feature is part of the Savonoski River Cluster of volcanoes, as defined by Hildreth and others (2004) [1]. From Hildreth and others (2004) [1]: "The largest of the mafic cones [in the Savonoski River volcano cluster] (54% SiO2), 2.5 km wide with 850 m of relief, is banked against a basement ridge just north of the snout of Hook Glacier. It consists of blocky and columnar lavas (132 +/- 27 ka), breccia sheets, and stratified scoria. Products contain orthopyroxene, magnetite, and abundant small plagioclase phenocrysts."
