Mount Vsevidof (or ; Russian: Вулкан Всевидова) is a stratovolcano in the U.S. state of Alaska. Its summit is the highest point on Umnak Island, one of the eastern Aleutian Islands. Its symmetrical cone rises abruptly from its surroundings. The base of the volcano is around 10km (10miles) wide, steepening from about 15 degrees at 300m (1,000feet) altitude to around 30 degrees near the summit. Some glacial tongues have cut through narrow canyons up to 120m (390feet) deep, due to ice filling the crater and extending down the north and east flanks of the cone.[1] Vsevidof's most recent eruption was caused by an earthquake on March 9, 1957. The eruption began March 11, and ended the next day.[2]

Its name comes from Russian words for “all” and “sight”, suggesting that it was implied to mean “seen from everywhere” or “where every place is seen from”.

Nearby towns to Vsevidof include Nikolski, Unalaska, Akutan, Atka and Anchorage.
