Black Peak is a highly eroded stratovolcano comprising a lava dome complex on the Alaska Peninsula of the U.S. state of Alaska. Also called Black Volcano or Sopka Chornaia, the mountain is located within the Lake and Peninsula Borough.
The latest eruption from Black Peak less than 4,000 years ago produced an explosive eruption with a Volcanic Explosivity Index of 6 that created a caldera. Ash flow tuffs and block-and-ash-flow deposits from this explosive eruption traveled down the Ash Creek and Bluff Creek valleys that reach depths of 100 m (328 ft).
