Lassen Peak Volcano
-- Geographic Setting, and Geologic and Eruptive History
In May 1914 Lassen Peak burst into eruption, beginning a seven-year cycle of sporadic volcanic outbursts. The climax of
the episode took place in 1915, when the peak blew an enormous mushroom cloud some seven miles into the stratosphere.
The reawakening of this volcano, which began as a vent on a larger extinct volcano known as Tehama, profoundly altered
the surrounding landscape.

Lassen Volcanic National Park
|
Lassen Volcanic became a national park in 1916
(106,000 acres), 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.
Lassen Volcanic National Park is located
fifty miles east of Red Bluff on highway 36, and 50
miles east of Redding on highway 44.
The 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.
Allow at least three hours to drive across the park and
to make stops.
The best time of the year to visit
for cross country skiing and snowshoeing is January,
February and March.
Snow covers much of the park mid October through early June. The
Lassen Park Road (the main road that connects Highway 89) is usually
closed late October through early June.
Many of the main park attractions are snow covered and
inaccessible by car and foot. July, August, and September may bring
mostly sunny skies with warm daytime temperatures and cold
nighttime temperatures.

The Lassen volcanic center is within the Lassen Volcanic National Park,
approximately 65 miles east of Redding, California, or 240 kilometers west of
Reno, Nevada. Access within the Park is by California Highway 89, which runs
through the volcanic center.

This trail is a well-graded climb of 2,000 feet, from 8,500 feet to
10,457 feet in 2.5 miles of hiking. Allow four hours for the round trip, though
some take more time, some less. For a pleasant hike:
- Wear low-heeled, sturdy shoes.
- Hike at a moderate pace, and take short, frequent rests. Enjoy
the ever-changing view!
- Take a lunch along. (Bring water)
- Dark glasses, sunburn lotion, a hat, and jacket are advisable.
- Do not start later than two hours before sunset, or when bad
weather threatens. Lightning frequently strikes the summit.
- DO NOT TAKE SHORTCUTS ACROSS THE TRAIL. It is prohibited
because:
a) It is dangerous. Strained muscles or broken bones can result.
b) Dislodged rocks are dangerous to hikers below.
c) It can cause landslides which destroy lower sections of trails. Remember,
your tax dollars rebuild trails destroyed by shortcutting.
