When & Why Lassen Volcanic became a National Park

Lassen Volcano became an official National Park on August 9, 1916. It was the 15th National Park. Since it was located in the most popular state at the time many towns people and ranchers visited it to camp and fish in surrounding land around Lassen Peak. It was great and people who lived near loved it, but it didn’t get many visitors from far away and it wasn’t likely to be a National Park for a long time. Then the volcano erupted and went dormant again. It soon became the most recent eruption in the United States. Still it was a small National Park, about only the size of 1/7 of Yosemite.

The Gold rush brought the first settlers to California. William Nobles and Peter Lassen made 2 pioneer trails. Parts of these trail are still in Lassen today. The park was named after Peter Lassen because he brought settlers here to try to build a city. Early on the area had been given protection that saved it from heavy logging. Even before then the Lassen area was a meeting place for a least 4 American Indian groups.

How Lassen Volcanic was Formed

About 27,000 years ago Lassen Peak started as magma (molten rock) on Mount Tehama. The magma came from inside the earth and flowed upwards, over years and years it formed Lassen Peak. Now it’s 11,000ft high and more that 11 miles wide. Eventually the great Mount Tehama collapsed helping form smaller mountains around it. Lassen Peak is one of these smaller mountains. The last time it erupted was in 1921. It was a small eruption and didn’t cause that much damage to people or the surrounding area. This was about 5 years after it became and official National Park.

Settlers came to Lassen Peak and saw the bubbling springs and vents spewing steam around Lassen Peak and assumed the volcano was extinct. The next year Lassen Peak erupted and the mountain top exploded. Now Lassen Peak is the most recent erupted volcano in the connected 48 states.
