4. When Lassen Became a National Park
Lassen became a National park on August 9, 1916
Roads and walkways were constructed between 1925 and 1931

5. Why Lassen Volcanic Became a National Park
Mountains by the Lassen roads reached feet, the highest peak in the cascade mountains.
Workers who constructed roads on these mountains felt Lassen was unique and special since it broke a record of being the highest cascade mountain.

6. Why Lassen Volcanic Became a National Park (Continued)
The workers told people who could make the decision of it becoming a national park and then the decision makers decided that it should become a national park

7. How Lassen Volcanic Was Formed
Lassen peak was once part of a much larger mountain named mount Teham that started 600,000 years ago as molten rock, known as magma.
Magma moved upwards from the depths of the earth slowly, over the years the magma formed a mountain estimated to be about 11,000 feet high with a base over 11 miles wide.
Eventually the great Volcano collapsed giving birth to an even smaller mountains around its rims. Lassen peak is one of the mountains that the Great Volcano gave birth to.
In the middle of the 19th century when the first settlers came over to California the area around the peak was dotted with bubbling springs and vents producing steam.

8. What Rocks You Can Find At Lassen Volcanic National Park
These are some rocks that are at my park and how you can identify them. Andesite- This piece of andesite rock is dark gray with lots of tiny white feldspar crystals imbedded in with the matrix of the rock Banded Pumice- This rock was formed in the eruption of Lassen Peak on may It is made up of layers of gray and black lava. Basalt- This lava rock is recognized by its dark gray color and has very small mineral crystals within its insides.

9. What Rocks You Can Find At Lassen Volcanic National Park(Continued)
Dacite-This rock is light to medium gray in its texture and has a very smooth texture. Typical of most Dacite lava rocks there are many visible mineral crystals with in its insides.
Rhyodiacite- Note the pink color and large mineral crystals of white feldspar.
Breccia- Breccia is a mixture composed of cinder ash, and broken fragments imbedded in andesitic lava. This rock has a reddish color and a chunky rough surface.

10. Special Landforms and Features Of Lassen Volcanic National Park
Lassen is one of the few places in the world where these four volcanoes can be seen: Cinder Cone, Composite, Shield, And Lava Dome
Cinder Cone- The most simple type of volcano. They are blobs and particles of congealed lava that is ejected from a single vent.
Composite- volcano are mostly steep-sided, symmetrical cones of large dimension made of bombs, blocks, cinders, volcanic ash, and lava flows.

11. Special Landforms and Features Of Lassen Volcanic National Park
Shield- Are formed from fluid lava that slowly builds up from many lava flows
Lava Dome-When the lava is blown into the air it breaks into little pieces that solidify and fall as cinders around the vent to form an oval or circular cone.

12. Special Landforms and Features Of Lassen Volcanic National Park (Continued)
They could rise up as much as 8,000 feet above their base.
A shield volcano is almost entirely built by fluid lava flows.
Lava dome volcanoes are formed by small, bulbous masses of lava that are too flow at a great distance.
A Lava Dome grows large by expansion from things that move around in the inside.

13. How Technology Is Used To Maintain Lassen Volcanic National Park
Recently at Lassen Volcanic National Park rangers have been using body cameras to record cases and park activity. The head of the rangers brought this idea all the way from Alaska. He thought it would be a great idea because he felt that better shots could be taken if the rangers were in control of the camera. People think this is a great Idea. “It is like a third witness” A park ranger said, with better audio and camera quality than our regular security cameras.

14. Extra info About Lassen Volcanic Becoming a National Park
The Lassen area was a meeting area for the Astugewi , Yana, Yahi, the Maidu Native American Groups.
After the Native Americans brought it to the explorer’s attention they talked and word got out about this very big mountain, they brought it to the attention of the people a who could make it a national park.And they did

15. Extra info About Lassen Volcanic Becoming a National Park
By 1900 some timber operations threatened many of the forests in the Lassen area.
On May 6, 1907 president Theodore Roosevelt declared Lassen Peak and Cinder Cone as national monuments.
In its early years, the park was pretty neglected by the government and little money was set aside for its administration
President Roosevelt declared Lessen a national park on August 9, 1916
