Establishment the Lassen Volcanic National Park

Lassen Volcanic was established as a national park 09 Aug 1916 because of its significance as an active volcanic landscape. Lassen Peak began erupting in 1914, had the most significant activity in 1915, and had minor activity until 1921. All four types of volcanoes in the world are found in Lassen’s 106,000 acres.

By the early 1900s local sentiment was building for the protection of Lassen Peak and Cinder Cone against commercial developement. In 1906 petitions from both Lassen and Plumas counties urged President Theodore Roosevelt to set aside the most significant features in the Lassen park are as national monuments. These recommendations eventually reached the desks of President Roosevelt, and on May 6, 1907, they were signed by the President. Lassen Peak and Cinder Cone became national monuments. While the Forest Service continued to manage the new sites, located within the Lassen National Forest, these two monuments formed the nucleus of the future park and gave recognition to Lassen Peak anc Cinder Cone as striking examples of volcanic activity.

The startling eruptions of Lassen Peak in 1914 and 1915 attracted national attention and stimulated local efforts to expand the origional monument into a national park. On August 9,1916, the US Congress passed a bill establishing Lassen Volcanic National Park, and President Woodrow Wilson then signed it into law.

Size and Visitation of Lassen Volcanic National Park

Lasson Volcanic National Park includes both of these earlier monuments as well as additional acreage aquired over the years. Today the park contains approximately 150 square miles, or over 106,000 acres.

Lassen Volcanic National Park is open year-round, however, access is difficult in winter and spring. The best time of the year to visit the park for hiking and car touring is August and September. The best time of the year to visit for cross country skiing and snowshoeing is January, February and March. The highest visitation is in August, with the lowest being in March.

Volcanic History

In May 1914, Lassen Peak burst into eruption, beginning a 7-year cycle of sporadic volcanic outbursts. The climax of this episode took place in 1915, when the peak blew an enormous mushroom cloud some 7 miles into the stratosphere. The reawakening of this volcano, which began as a vent on a large extinct volcano known as Tehama, profoundly altered the surrounding landscape. The park is a compact laboratory of volcanic phenomena and associated thermal features except true geysers. It is part of a vast geographic unit – a great lava plateau with isolated volcanic peaks – that also encompasses Lava Beds National Monument, California, and Crater Lake National Park, Oregon.

Plant Life at Lassen Volcanic National Park

The park’s plant life mixes species of the Sierra Nevada to the south and the Cascade Range. The result is a relative abundance of species. The park boasts some 779 plant species, but nearby Mount Shasta has only 485 species. About 24 Sierran species are at the northern limit of their range here. About 14 Cascadian species are at their southern limit.

Catastrophic events that created the Devastated Area and Chaos Jumbles also created Hat and Manzanita Lakes. These are indeed fortunate landscape recoveries for today’s park visitor. Hat Lake is undergoing succession too. Rapidly filling with debris from higher elevation Hat Lake will soon disappear, leaving a meadow that will one day give way to forests.
