My visit to Lassen Volcanic National Park on a trip south to visit family.

Lassen_Volcanic_National_Park_map

I left Vancouver for southern California and my first overnight stop was Lassen Volcanic National Park in northern California. As the name implies it’s major features are volcanic in origin. Being the southern most volcano of the Cascade Range the prominent features of the park are the largest plug volcano in the world, Lassen Peak and it’s sulfur – thermal hot springs.

Originally two separate National Monuments dedicated in 1907 by Theodore Roosevelt, Cinder Cone and Lassen Peak National Monuments were declared Lassen Volcanic National Park in 1916.

I arrived late in the afternoon after an 8 1/2 hour drive and set up camp at Manzanita Lake Campground located in the northern section of the park. Then I proceeded to walk the loop trail around Manzanita Lake, ate dinner and enjoyed a nice campfire before retiring to my tent to read and fall asleep.

 

Accessible by five vehicle entrances the majority of visitors enter either from the north or south along State Route 89, named the Volcanic Legacy Scenic Byway or Lassen Volcanic National Park Highway, off State route 44 in the north and 89 from the south. Three unpaved roads enter the park but do not connect with the main road through the park, Highway 89.

The north-south 29-mile (46.6k) road, Highway 89, was constructed between 1925 and 1931. The road summit is the highest in the Cascades topping at 8,512 feet (2,594 m). This road is closed in the winter months due to snow, which can reach 40 feet (12.2m) deep.

Early morning along the Lassen Volcanic National Park Highway

 

I got up early, had a quick breakfast and packed up to head south along Route 89 to visit the sites of the park. It was very interesting stopping at the many informative signs along the road to read the history of the park.

 

The last minor to major eruption started in 1914 and lasted until 1921 creating a new crater on Lassen Peak. Releasing ash and lava it fortunately did not kill anyone. This eruption covered many miles of forestlands with landslides and the new growth forest today stands many feet above the old forest floor. These landslides also created Manzanita Lake as it damned Manzanita Creek.

The first blast was on May 19, 1915 and was said to be a night to remember with it’s steam explosion and subsequent mudflows. Had it not been for Elmer Sorahan many people might have died but he ran 3 miles (4.8k) to warn others after escaping the explosion.

 

Three days later on May 22, 1915 another explosion on Lassen Peak threw ash, pumice, rock and gas into the air that was more devastating to the area than the first. The pressure in the mountain built up like a lid on a boiling pot of water and finally blew. You can now explore this area on a ½ mile (0.8k) loop trail or take the strenuous 2,000 foot (609.6m) 5 mile (8k) round trip hike to the top of 10,457 foot (3,187m) Lassen Peak. Many other hiking opportunities exist in the park along with backpacking, auto-touring, bird watching, camping skiing, skiing, snow play, and snowshoeing.

There are 5 hydrothermal areas to explore within the park. Sulphur Works, Bumpass Hell, Devils Kitchen, Boiling Springs Lake and Thermal Geyser. I am limiting myself to 2 for this trip.

My first hydrothermal area would have been the hike out to Bumpass Hell Hydrothermal Area, a moderate 3 mile (4.8k) round trip hike. This is the largest hydrothermal area of the park with temperatures of up to 322 degrees F (161 degrees C). I had done this hike with my kids back in the early 1990’s although I found the trail closed this season for maintenance of the trail and boardwalk through the 2018 season.

My next stop was Sulphur Works, a formation of mudpots, steam vents and boiling springs located right off the main road. This hydrothermal area in near the center of a massive composite volcano that collapsed many thousands of years ago. Mount Tehama or Brokeoff Mountain was estimated to be 1,000 feet (304m) higher than Lassen Peak. Active 400,000 to 600,000 years ago it is estimated to be nearly 11 miles (17.7k) across and had towered to 11,500 feet (3,505k).

 

My final stop was the Kohm Yah-mah-nee Visitor Center at the south entry of the park to visit the small museum learning the history of the park, peoples and area and had a nice talk with the Rangers.

Now for the long 8 hour drive down the east side of the Sierra Nevada Mountains along State highway 395 to the BLM area of Alabama Hills outside of Lone Pine, CA.
