Summary
Quick Facts

Lava flows from two isolated cinder cones northwest of Lassen Peak blocked drainages, forming three small lakes. The cones lie southwest of Burney Mountain and west-northwest of Magee Peak. Lava flows from the Silver Lake cinder cone formed Silver Lake northeast of the cone and crescent-shaped Arthur Lake to the east and traveled 3.5 km (2.2 mi) to the southwest. The crater of Silver Lake cone is open to the southwest. The flat-topped Buckhorn Lake cinder cone to the southeast of Silver Lake dammed up Buckhorn Lake, northeast of the cone, and produced a lava flow that traveled 3.5 km (2.2 mi) to the southwest. These basaltic cones are of possible Holocene age, but lie outside the area of glaciation at Lassen and their age is not known with certainty.
