Mount Vsevidof (/ˌvɪzəˈviːdɒf/ or /vəˈʃeɪvɪdɒf/;[4] 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 10 km (6 mi) wide, steepening from about 15 degrees at 300 m (980 ft) altitude to around 30 degrees near the summit. Some glacial tongues have cut through narrow canyons up to 120 m (390 ft) deep, due to ice filling the crater and extending down the north and east flanks of the cone.[5] It is most likely that Mount Vsevidof has not erupted in historic time. Reports of its latest eruption in 1957 is considered questionable by the Alaska Volcano Observatory.[6][Notes 1] This also includes possible eruptions or activity which may have occurred at the volcano in 1784, 1790, 1830, 1878, and 1880.[6]

The theory that 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”, seems incorrect. The vocano was discovered by the Russian explorer Gavriil Pribylov, who navigated the Aleutians between 1773 and 1786, likely named the volcano to honor of the Russian explorers - either Andrew Vsevidov or Piotr Vsevidov, both of whom made significant contributions to the exploration of the Aleutian Islands during the 1740s and 1750s.

Nearby towns to Vsevidof include Nikolski, Unalaska, Akutan, Atka and Anchorage.[5]
