The last major eruptions of Lassen Peak occurred in April through June 1917, when a new crater was created at the summit of the mountain. Less explosive activity continued through 1921. [ 1 ] [ 24 ] The Smithsonian considers the eruption of Mount Lassen to have ended on June 29, 1917.
California's last major destructive volcanic eruption came more than a century ago. Lassen Peak underwent a series of eruptions between 1914 and 1917.
The 29 mi (47 km) Main Park Road was constructed between 1925 and 1931, just 10 years after Lassen Peak erupted. Near Lassen Peak the road reaches 8,512 ft (2,594 m), making it the highest road in the Cascade Mountains. It is not unusual for 40 ft (12 m) of snow to accumulate on the road near Lake Helen and for patches of snow to last into July.
Loomis was a local homesteader and photographer who documented the 1915 eruptions of Lassen Peak, and was instrumental in the 1916 establishment of the national park. In 1929 Loomis donated the museum and 40 acres (16 ha) of surrounding lands to the National Park Service , which since then has used the structure as an interpretational facility.
A year before Ishi's death, Mt. Lassen exploded. Mt. Lassen is officially recognized as Lassen Peak by the United States Board on Geographic Names. Before the eruption on May 22, 1915, the smoking volcano became a tourist draw. Today, within Lassen Volcanic National Park, the area surrounding the volcano is known as the Devastated Area.
