The Hogum Range contains a group of at least 7 volcanic necks which are associated with dikes, lava flow remnants, and pyroclastic cones. Some of the cones contain striated boulders, occur in places where they would have been destroyed by Pleistocene glaciers, and are considered to be of Recent age by Lord (1948). Souther (in Wood and Kienle, 1990) indicates that the relationship of intravalley flows to the present topography suggests a Quaternary age. Recent work indicates all activity ceased during the Pleistocene (Hickson et al., 1994).
