A black and white photograph looks across a swath cut through a pine forest by a debris and mud flow that originates at a steaming volcanic peak in the distance. A large crater is visible on the side of the volcano, which is emitting the steam. The rest of the volcano is heavily blanketed in snow.

Steam issuing from summit of Lassen Peak from head of Lost Creek following mudflow. "Hot Rock"(large boulder) in foreground. Photographs taken a few hours prior to second major eruption and hot blast.

In a black-and-white photo, a snow-covered mountain peak is streaked with dark mud flowing down its sides in three directions. One flow directly faces the viewer, showing where trees have been mowed over by the debris. Elsewhere on the slopes, pine trees are scattered through the snow.

A second view of Lassen Peak and the Deveastated Area following an explosive eruption and mudflowk. The crater of the volcano is visible, revealing that a lava dome which had previously been growing there was destroyed by the explosion. Subsequently, a lava flow began refilling the crater, and was mistakenly thought to have created the mudflow.
