Mount Gilbert, Stratovolcano on Akun Island, Alaska, US

Mount Gilbert is a stratovolcano on Akun Island in Alaska, rising with steep slopes and heavily eroded northern flanks that dominate the landscape. The volcanic cone creates a dramatic profile on the northern portion of the island.

The mountain was first recorded in 1947 in a coastal guide, possibly named after John J. Gilbert, a steamer captain from the early 1900s. The island itself has long been inhabited by people adapted to life in this volcanic setting.

The mountain carries the geological story of the Aleutian Islands, and its rock formations show traces of ancient volcanic activity that shaped the communities living in this region.

Reaching this mountain requires air or water transport since the island is remote and far from major settlements. Visitors should expect harsh weather conditions typical of the Aleutian Islands.

Active fumaroles were documented about 1.5 km northeast of the summit in the early 1900s, and the Polish Wikipedia places the last observed fumaroles around 1900. The volcano forms the northern part of Akun Island in the eastern Aleutians and rises to 818 m.
