From Miller and others (1998) [1] : "Isanotski volcano, located near the eastern end of Unimak Island, is a dissected, snow- and ice-covered stratovolcano with a basal diameter of about 10 km. It is much more deeply eroded than neighboring Shishaldin volcano and lies between Shishaldin and Roundtop along a roughly east-west alignment."

Name Origin

"Isanotski Peaks" was derived from Isanotski Strait, and published by Captain Tebenkov as "Sop[ka] Isanotskaya" meaning "Isanotski Volcano". Isanotski is an Unangam Tunuu name reported by Captain Lutke (1836) as "Issanakh" from the word "isanaq" which, according to R.H. Geoghegan, means "tear (split or strait)" (Orth, 1971). Bergsland (1994) reports the Unangam Tunuu placename as "Iisan."
