Pink-orange, semi-continuous pods that are ~0.5 to 3 cm thick and are within, or up to 40 cm below, the base of the Matheus and others (2003) middle peat. Glass morphology is distinct: dominantly thick-walled pumice contain such abundant microlites that vesicles are deformed, and pure glass analyses are difficult. Some brown glass is present, and mineralogy consists of plagioclase, which is frequently zoned, and pyroxene.
