Description

From Miller and others (1998) [1] : "Trident is an eroded volcanic complex consisting of three stratovolcanoes and numerous domes, as high as 1864 m in elevation, along a northeast-southwest oriented volcanic front on the Alaska Peninsula [2] . A new fragmental cone was built beginning in 1953 at an altitude of 1097 m in an amphitheater on the southwest flank of the southwest peak."

Name Origin

"Trident Volcano" is a descriptive name given by R.F. Griggs in 1916, because of its three prominent peaks (Orth, 1971).
