The western terminus of the Hoffman dacite lava flow forms a steep blocky slope up to about 50 m in height. The flows originated from six or more NW-SE-trending vents. The larger of the two flows (seen here) was erupted near the eastern caldera rim and flowed primarily west into the caldera, although a smaller portion traveled to the east.
