Description

From Wood and Kienle (1990) [1] : The "Morzhovoi Volcanics constitute a late Pliocene to early Pleistocene basaltic and andesitic stratovolcano. Volcanism culminated in the formation of a large collapsed crater. Though presently ice-free, extensive Pleistocene glaciation has eroded most original stratovolcano features, including the actual crater rim, leaving long U-shaped valleys." From Myers (1994) [2] : "The oldest volcano [of the Cold Bay Volcanic Complex] Morzhovoi Volcano, is of late Tertiary to Quaternary age, lies on the southern edge of the Alaska Peninsula, and consists of basalts, andesites, and associated pyroclastic rocks (the Morzhovoi Volcanic Series). Because it has undergone extensive erosion, only remnants of the volcano remain. Isolated peaks, e.g. North and South Walrus Peaks, that are fragments of the original caldera rim range in height from 797 to 893 m."

Name Origin

"Morzhovoi volcanics" is an informal name, named after the nearby Morzhovoi Bay. Captain Tebenkov named the bay "Za[liv] Morzhovoi" in 1852, meaning "Walrus Bay" (Orth, 1971).
