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] : "Cone 3110 is a basaltic pile (51% SiO2) about 2 km wide with 675 m of relief that lies a few km NW of Cone 3601. Partly erupted englacially, it consists mostly of massive to sheeted glassy breccia and coarse stratified scoria that dip chaotically and enclose channel fillings of convolutedly columnar glassy lava. The upper third of the cone (235 +/- 30 ka) is coherent lava, columnar to chunky jointed. Products have abundant plagioclase, clinopyroxene, and olivine, with minor orthopyroxene."

Name Origin

Cone 3110 is an informal name given by Hildreth and others (2004).
