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).
