Why Mt. Lassen is what it is instantlyLassen period, also known as Mount Lassen, is the southernmost active venthole in the cascade Range. It is part of the Cascade Volcanic Arc which is an flicker that covers southwestern British Columbia to northern California. Located in the Shasta Cascade region of Northern California, Lassen rises 2,000 meters above the surrounding terrain and has a volume of 0.5 box-shaped miles, making it one of the largest lava domes on Earth. It was created on the destroyed northeastern font of now gone Mount Tehama, a stratovolcano that was at least 1,000 feet high than Lassen bloom.Lassen Peak was named in honor of the Danish blacksmith Peter Lassen, who guided immigrants past times this peak to the Sacramento Valley during the 1830s. His trail never found planetary long-term use because it was considered unsafe. This trail was replaced by the Nobles Emigrant Trail, named for the guide, William Nobles. In 1864, Helen tan Brodt became the first w oman to reach the summit of Lassen Peak. A tarn lake on Lassen Peak was named Lake Helen in her honor. In the 1914 to 1921 time zone, Lassen Peak emerged from inactivity with a series of steam outbursts, dacite lava flows, and volcanic mud flows. There were 200 to 400 volcanic eruptions during this period of activity. Because of the eruptive activity and the areas brilliant volcanic beauty, Lassen Peak, Cinder cone shape and the area surrounding were designated as the Lassen Volcanic National Park on August 9, 1916. Mt. Lassen eruptionsOn May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east This explosion was the most powerful in a series of eruptions from 1914 through 1917. ... ...e than 30 volcanoes that have erupted over the past 300,000 years in the Lassen Peak volcanic area.6. Lassen Peak has the highest known winter snowfall amounts in California. There is an ordinary annual snowfall of 660 in, an d in some years, more than 1,000 inches of snowfall at its base altitude of 8,250 feet at Lake Helen.7. The Mount Lassen area receives more temerity than anywhere in the Cascade Range south of the Three Sisters volcanoes in Oregon.8. The heavy annual snowfall on Lassen Peak creates fourteen everlasting patches of snow on and around the mountain top, despite Lassens rather nonaged elevation, but no glaciers. 9.Lightning has been known to strike the summit of the volcano ofttimes during summer thunderstorms.10.Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
