Why are parks so important? They are important to protect the landscape extraordinary wildlife and majestic forests.

Extraordinary means very unusual or remarkable

tow endangered species is the bighorn sheep, the California wolverine, and the red fox

Half Dome

The reason its called half dome is because the other half of the rock fell off

Yosemite is right on the North American Plate and is pushing on the Pacific Plate, as they pushed it pushed the pacific plate in a hot mantle and melted which created Half Dome

a geologist say what happened to the other half of the dome was called exfoliation.

exfoliation is separation of successive thin shells or spalls from massive rock such as granite or basalt; it is common in regions that have moderate rainfall. you can climb on half dome.

Half Dome is made of Glacially-polished granite

There is Layered metamorphic rocks in the foothills at the west edge of the park

Some people jack around on the Half Dome ropes which they may or could or have fall/fallen off the rope and died

Timeline of Yosmite

65 million years ago- Yosemite is a place where the dynamism of geologic processes in well displayed by the end of Cretaceous time

25 million years ago- this lowland area began to be uplifted and tilted toward the southwest, a construction that would eventually lead to the present sierra Nevada

About 10 million years ago-the faster flowing streams cut deeper and deeper canyons into the mountain block

2-3 million years ago- the sierra Nevada had risen high enough for glaciers and mountain ice field to form
