B.F. Loomis reported that the rock in this photo was “still sizzling in the water” some forty hours after it was ejected from the volcano’s crater.
The destructive forces that moved this cabin-size rock destroyed a three-square-mile swath, now called the Devastated Area. Visit the Devastated Area Trail two miles south of here.

Following the May 1915 Lassen Peak eruptions, B.F. Loomis and other local residents discovered several massive hot rocks resting in the valley miles from the volcano. This hot rock is a piece of dacite lava that filled Lassen Peak’s crater. On May 14, 1915, lava began welling up and plugged the volcano’s crater. Pent-up gases within the volcano blasted and shattered the lava cap on May 19.Careening down the mountainside, hot lava rocks touched off a snow avalanche. The avalanche carried this 300-ton rock five miles from Lassen Peak to this location, where it settled, sizzled, and cooled.
