The Lassen volcanic center consists of the andesitic Brokeoff stratovolcano SW of Lassen Peak, a dacitic lava dome field, and peripheral small andesitic shield volcanoes and large lava flows, primarily on the Central Plateau NE of Lassen Peak.

Partial collapse of the eruption column that fell onto the northeastern slope of Lassen Peak generated a high-speed flow composed of hot ash, pumice, rock fragments, and gas—called a pyroclastic flow—that swept down the side of the volcano, devastating an area of 3 square miles.

• Andesite (52-63% Silica) This type of lava rock is typically associated with composite volcanoes.
• Basalt (<52% Silica)
• Dacite (63-69% Silica)
• Scoria (Cinder)
• Rhyolite (>69% Silica)
• Pumice.
• Please do not remove rocks from the park.
• Hydrothermally Altered Rocks.

The Fantastic Lava Beds are amazing. It is one of the few places where you can see an entire geologic process right before your eyes. Standing atop cinder cone you can see where the lava who’s got out from the base of the cone.

However, Lassen Peak is considered active because it last erupted about 100 years ago (read more). Geologically recent volcanic activity in an area is the best guide to forecasting future eruptions.

Swimming and picnic area on the north shore of Summit Lake. Swimming and wading is allowed in park lakes and creeks, except park hydrothermal areas. …

In one day, you can drive through the park, visit a couple of hydrothermal sites (Bumpass Hell and Sulphur Works are the best areas to visit on a short trip to the park), have a picnic by one of the lakes, and perhaps do a short day hike (Lassen Peak or Kings Creek Falls are great choices).

This off-the map treasure located near the small town of Chester offers crystalline lakes, stunning mountains, steaming fumaroles, flower-filled meadows, and the striking volcanoes for which the park is named. Though it is lesser known, this Park is certainly worth the trip.

One to Five Days in Lassen Volcanic National Park. Established in 1916 as the 15th National Park, Lassen is only 20 miles from St. Bernard Lodge. We have many suggestions for how to experience this treasure whether you are coming for the day or spending the week.

Camping in a park campground is the primary form of accommodation in Lassen Volcanic National Park. Camping cabins are available only at Manzanita Lake Campground. Drakesbad Guest Ranch provides the only lodging in the park.

Carnivores are perhaps the most widely recognized group of mammals in Lassen Volcanic National Park. Its members include the American black bear, bobcat, mountain lion, raccoon, coyote, fox, weasel, and skunk. Lesser known species like the American marten and ringtail are also present.

Yosemite National Park is approximately 167 miles east of San Francisco. Depending on how you choose to get there, travel time will take an average of 3 ½ – 4 ½ hours.

The ideal season for visiting Lassen Volcanic National Park is pretty short: usually the roads through the park open in July, when the snow melts, and then snow starts to set in again around October.

The best way to get to Redwood National Park out of San Francisco is the fastest, and the most straightforward. All you’ll do is head out of San Francisco along the Golden Gate Bridge. Pass Fort Baker and stay on the US-101 for the entire drive, until you reach Redwood National Park.

The distance from San Francisco to the redwood forest and natural wonders of Yosemite is about 170 miles each way. That is about 8-10 hours driving round trip.

Muir Woods

Sequoias and giant redwoods are often referred to interchangeably, though they are two very different, though equally remarkable, species of tree. Both naturally occurring only in California, these two species share a distinctive cinnamon-colored bark and the proclivity for growing to overwhelming heights.

Shape and size. —The giant sequoia is the largest tree in the world in volume and has an immense trunk with very slight taper; the redwood is the world’s tallest tree and has a slender trunk. —The cones and seed of the giant sequoia are about three times the size of those produced by the redwood.

Redwoods are the tallest trees in the world. Sequoias are the biggest, if measured by circumference and volume. Redwoods can grow over 350 feet (107 m). The tallest tree in the world that we know of is called the Hyperion, and it tickles the sky at 379.7 feet (115.7 m).

The tallest trees in the world are redwoods (Sequoia sempervirens), which tower above the ground in California. These trees can easily reach heights of 300 feet (91 meters). Among the redwoods, a tree named Hyperion dwarfs them all. The tree was discovered in 2006, and is 379.7 feet (115.7 m) tall.

globosa are similar in size and are the smallest fruits on earth. Certain epiphytic orchids of the tropical rain forest produce the world’s smallest seeds weighing only 35 millionths of an ounce.

Mangoes are the sweetest fruits known. As per the Guinness Book of World Records, the carabao mango is the sweetest of all. Its sweetness is derived from the amount of fructose it contains.
