|Old Giants: red dacit formed at Lassen_Peak 27,000 years ago|
The Devastated Area Interpretive Trail in Lassen Volcanic National Park, California, is a short, wheelchair-accessible loop trail with interpretive and audio exhibits that feature aftermath evidence of Lassen Peak's catastrophic eruptions in May of 1915. Businessman, photographer, and author, Benjamin F. Loomis—Lassen Park's Loomis Museum is named in memory of his daughter Mae—came to inspect this area after one eruption, when the next one was following. An on-site panel describes that event:
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. They were astounded by what they saw, but could not suspect that 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.
Other exhibits along the loop trail showcase the legacy of B. F. Loomis, who photo-chronicled Lassen Peak's eruptions and glowing lava rocks. Further exhibits illustrate the mixing and solidification of basalt-injected dacite lava and the fracturing of cooling rocks into jigsaw-puzzle-like pieces.
