Devils Garden, part of which forms the jumbled blocky lava flows in the foreground, is part of the N-S-trending Tumble Buttes, a young volcanic field located north of Lassen Peak. The Tumble Buttes field contains some of the youngest volcanic features in this little known area partially within the Thousand Lakes Wilderness Area west of the Hat Creek Valley. The andesitic lava cone at the upper right is Logan Mountain, of Pleistocene age.
