A N-S-trending chain of vents extending across the center of the photo forms Tumble Buttes, a young volcanic field north of Lassen Volcanic National Park. A large area of unvegetated lava flows at the left margin originated from Bear Wallow Butte at the southern end of the chain. Other young unvegetated flows form the Devils Rock Garden at right-center, below Crater Mountain, the prominent snow-dappled peak on the horizon. This view looks to the NW across the Hat Creek valley from West Prospect Mountain.
