Meager Mountain

The northern segment of the Garibaldi Belt includes the Meager Mountain complex and several remnants of basaltic and andesitic piles which extend north of Meager Mountain almost to the Interior Plateau. Meager Mountain (Read, 1978; Lewis and Souther, 1978) is a complex of at least four overlapping composite dacite to rhyodacite volcanoes that become progressively younger from south to north, ranging in age from approximately 2 million years to around 2,490 years old. -- Souther, 1990, IN: Wood and Kienle |

Crater Lake

Crater Lake caldera formed by collapse during the catastrophic eruption of approximately 50 cubic kilometers of magma, 6,845 carbon-14 years B.P. (before present). The 8x10 kilometer caldera lies in the remains of Mount Mazama, a Pleistocene stratovolcano cluster covering 400 square kilometers in the southern Oregon Cascades. Prior to its climactic eruption, Mount Mazama's summit had an elevation between 3,300 meters and 3,700 meters (10,800 - 12,000 feet). Its southern and southeastern flanks were deeply incised by glacial valleys, now beheaded, that form U-shaped notches in the caldera wall. -- Bacon, 1990, IN: Wood and Kienle

Medicine Lake
2,412 meters
|
The Medicine Lake shield rises about 1200 meters above the Modoc Plateau to an elevation of 2,376 meters. Lavas from Medicine Lake volcano cover nearly 2000 square kilometers, and their volume is estimated to be at least 600 cubic kilometers, making it the largest volcano by volume in the Cascade Range. -- Dzurisin, et.al., 1991
Glass Mountain consists of a spectacular, nearly treeless, steep-sided rhyolite and dacite obsidian flow that erupted just outside the eastern caldera rim and flowed down the steep eastern flank of Medicine Lake volcano. Ten additional small domes of Glass Mountain rhyolite and rhyodacite lava lie on a N25degreesW trend to the north and one to the south. The age of Glass Mountain and its preceding pumice deposits has been a matter of discussion for some time. A radiocarbon age of 885+/-40 years B.P. was obtained on a dead cedar tree without limbs or bark that is preserved in the edge of one of the distal tongues of the flow. The dated material consisted of a piece of exterior wood containing about 30 annual growth rings. This age may be too old, because some of the outside of the tree is missing. The tephra deposits that precede the flow and domes may be somewhat older but are constrained to be less than about 1050 years B.P. by the Little Glass Mountain and Lassen data. -- Donnelly-Nolan, 1990 |

Mount Shasta, a compound stratovolcano rising 3,500 meters above its base to an elevation of 4,317 meters, dominates the landscape of northern California. ...
