Bear Wallow Butte, the forested peak at the right, was the source of the youthful-looking unvegetated lava flows seen at the left-center. Bear Wallow Butte lies at the southern end of a N-S-trending chain of vents known as Tumble Buttes. Snow-capped Lassen Peak is visible to the south just beyond the summit of Bear Wallow Butte.
