Overview
The heavily glaciated Recheschnoi stratovolcano is located ENE of a roughly 900-m-high saddle across from Vsevidof volcano. It consists of an elongated, NE-SW-trending ridge dissected by deep glacier-filled valleys; erosion is more extensive at the NE end. Holocene andesitic pyroclastic cones and rhyolitic lava domes, the latter west of the head of Russian Bay, are situated on the E and W flanks.
The Geyser Bight geothermal area on the NE flank consists of six zones of thermal springs and two fumarolic areas along upper Geyser Creek, and contains the only known geysers in the state. Other thermal areas occur at Hot Springs Cove and Partov Cove on the isthmus between Recheschnoi and Okmok.

About the Photo
Mount Recheschnoi on Umnak Island has been extensively eroded by glaciers. This 1985 view from the SW shows the NE-SW-trending summit ridge, which is contains deep valleys. Holocene cones and lava domes are on the E and W flanks, and a large thermal area including hot springs and a geyser is on the NE flank.
