Isanotski, Shishaldin, and Westdahl Volcanoes, Unimak Alaska

by Michael Jackson, UNAVCO, Boulder, USA

Photo taken looking west from Round Top, an eroded and glaciated stratovolcano, located 13 km southwest of the village of False Pass on Unimak Island. Foreground left is Isanotski a dissected, snow- and ice-covered stratovolcano. In the middle right is Shishaldin, symmetrical and highly active stratovolcano and is flanked by numerous parasitic cones. Background center Westdahl Peak, including nearby Faris Peak and Pogromni volcano, is located on a gently sloping plateau that may represent the surface of a truncated ancestral cone.
