There is the famous Mt Shasta. It was created by a combination of explosive activity and lava flows. It has lots of peaks such as the Gray Butte, the Misery Cone, Sargents Ridge Cone, and the Shastina. Mt. Shasta was a stratovolcano, but somehow turned into a mountain. There are also some other famous ones like the Black Butte, Clear Lake, Glass Mountain, Amboy Crater, and Lassen Peak.

The Pangea
Pangea was one super continent that was on the earth 200,000,000 years ago. The word Pangea means 'all land' in Greek. The pieces that made up this super continent split up and drifted slowly apart, and became the seven continents today.
Scientists say that they knew there was Pangea because there were the same matching fossils that were found in Africa and South America. Also, all the continents would fit almost perfectly together like a jig-saw puzzle.
