Background

Miller and Richter (1994) noted that Jarvis is the high point of a slightly curvilinear, N-trending, 10-km-long, 4,000-m-high ridge. The ridge, covered in snow and ice, consists of a thick sequence of dacitic and andesitic lava flows and capped by either a massive dacite flow or by a series of smaller dacite domes. One K-Ar age on possible basal flows suggests an age of about 1.6 Ma (Richter and Smith, 1976).
