Description
From Miller and Richter (1994) [1] : "This mountain is the high point of a slightly curvilinear, north-trending, 10-km-long, 4,000-m-high ridge. The snow- and ice-covered ridge is composed 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 basal (?) Jarvis flows suggests an age of about 1.6 M [2] ."Name Origin
Mount Jarvis was named in 1903 by F.C. Schrader, for Captain D.H. Jarvis, who spent several years in Alaska (Orth, 1971).
