Goosenest is a shield volcano topped by a pyroclastic cone at its summit located in the Cascades of northern California.[1] The area is near Mount Shasta, and represents one of the region's short-lived shield volcanoes, although Goosenest is a larger and longer-lived example. Its volcanic edifice comprises basaltic to basaltic-andesitic lava flows, a rare feature for the area.[2] The volcano has a volume of 10 km3 (2.4 cu mi) and produced lava flows covering 60 km2 (23 sq mi).[3]
