B.F. Loomis, eyewitness and photographer
This photo of the Devastated Area was taken by B.F. Loomis just a few days after the May 19th volcanic destruction and just a few hours before Lassen Peak’s greatest eruption, May 22, 1915.
[Two markers, side-by-side, describe the events that created the Devastated Area.]

Marker 1:
A Night to Remember
May 19, 1915
You are standing in the aftermath of the volcanic destruction known as the Devastated Area. Late on the evening of May 19, 1915, a large steam explosion shattered the lava that filled Lassen Peak’s crater the previous days. Glowing blocks of hot lava fell on the summit and snow-covered upper flanks of the volcano. The impact touched off an avalanche of snow and lava rocks a half-mile wide. It roared down the volcano’s flank in front of you and continued up and over Emigrant Pass behind you.

As the lava blocks broke into fragments, the snow melted, creating a mudflow and volcanic debris, called a lahar. Though with less force, the torrent rushed down the path of the avalanche and was deflected by Emigrant Pass into Lost Creek, sweeping through homsteads.

Had it not been for the heroics of Elmer Sorahan, who narrowly escaped the flood and ran three miles to warn others, many people might have died. As it was, no lives were lost, though six homesteads were destroyed.

In the night his dog barked, raved and stuck his paws against wake him up. Elmer thought it might be...a bear

The eruption came on gradually at first, getting larger and larger until finally it broke out into a roar like thunder.... [T]he smoke cloud ran down the mountain side, melting the snow very fast, and the water could be seen running a rush twenty feet wide.

or panther, so he got up...He..,peeped out to see what the dog was barking at. He saw the mud flow coming like a wave about twelve feet high....

Marker 2:
Three Days Later
May 22, 1915
The volcano’s crater welled up again with lava following the May 19th eruption. Like a lid covering a boiling pot, the pressure built. This time it erupted with even greater force. The blast hurled rock fragments and pumice (lava filled with gas bubbles) high into the air. A huge column of volcanic ash and gas rose more than 30,000 feet and could be seen 150 miles distant.

The falling pumice created yet another avalanche, a pyroclastic flow of hot ash, pumice, rock fragments, and gas. The avalanche rapidly gathered and melted snow in its path, transforming into a highly liquid lahar and following the path of the May 19th lahar or mudflow. It rushed miles down Lost Creek, flushing volumes of water into lower Hat Creek Valley once again.

On May 22, 1915, an explosive eruption at Lassen Peak, California, the southernmost active volcano in the Cascade Range, devastated nearby areas and rained volcanic ash as far away as 200 miles to the east.

Devastated Area Trail
This ½-mile loop trail circles through a small portion of the Devastated Area, showcasing aftermath evidence of Lassen Peak’s May 1915 catastrophic eruptions.
To ground yourself in the overall Lassen Peak eruption story, visit the two exhibits at the edge of the parking lot before walking the trail.

On May 22, 1915, seven men, including photographer B.F. Loomis passed near here while inspecting the damage that followed Lassen Peak’s May 19 eruption. The were astounded by what they saw, but could not suspect the horrific scene would be repeated just hours later. Had they dallied they might not have survived, for Lassen Peak blew again at 4:45 p.m. that afternoon.

Mudflows that were triggered on May 19 and 22 swept through Lost Creek. Notice the man standing in the creek bed in the photo (far left). The freshly cut banks are five times as high as the man is tall.

A few cabin-size lava rocks (near left), blasted from Lassen crater and carried more than four miles by the May 19th avalanche, rest as monuments throughout the Devastated Area.
