Lassen Volcanic National Park protects over 106,000 acres at the southern end of the Cascade Range in northern California, including Lassen Peak. Lassen Peak, southernmost in a string of legendary volcanoes (Shasta, Hood, St. Helens, Rainier, Baker) in a range that stretches north to British Columbia, is quiet today, but it was in the midst of an eruption just a century ago. In 1907, the year after passage of the Antiquities Act gave him the power, President Theodore Roosevelt declared two National Monuments in the Cascade Range east of Redding, California: Lassen Peak National Monument and Cinder Cone National Monument. Seven years later, in May 1914, long dormant Lassen Peak began to erupt (after an estimated 27,000 years of inactivity). The following year, in May 1915, the mountain exploded, sending a column of ash and steam 30,000 feet into the air and partially collapsing in on itself with flows of mud, ash, and pumice traveling some twenty-five miles from the crater. Major steam eruptions continued into 1921, with some 400 total eruptions between 1914 and 1921. In August 1916 with the eruption very much ongoing, President Woodrow Wilson signed legislation combining the National Monuments and expanding them into Lassen Volcanic National Park.

Lassen Volcanic National Park had long been among the Parks I’d been most excited to visit in this whole journey. In fact, more often than not, I’d cited it as the Park I was most excited to visit. Now just past noon on Friday, September 13, having finished packing up our campsite on the beach, we were on our way there.
