"The desire to observe a volcanic landscape in process was one of the driving forces behind the creation of Lassen Volcanic National Park. Certainly, one of the best areas from which
to witness the destruction volcanic forces are capable of is the Devastated Area on the northeast slopes of Lassen Peak. On May 19, 1915, hot lava spewed from Lassen Peak, melting the deep snowpack and propelling a half-mile-wide, 20-foot-deep mass of slush and rock down the mountainside and into the canyons of Lost and Hat Creeks.
Three days later, the volcano erupted, sending a desiccating cloud of vaporized lava and superheated gas down the course of the mudslide, ?attening every tree still standing, resulting in a swath of destruction 1.25 miles wide and 5 miles long, which eventually garnered the name Devastated Area. After a hundred years, the sight is not as devastating as it once appeared, with a scattered forest of Je?rey pines springing out of the sandy soil, softening the former bleakness."
