외계행성같은 Lassen-Volcanic National Park

Lassen-Volcanic National Park, located in the US state of California, is one of the few places on Earth

where you can see all four types of volcanoes

: the lava cone, the slag cone, shield volcano and stratovolcano. 

However, the main attraction of the park are the multi-colored dunes, which were formed as a result of

the oxidation of volcanic ash.
