23 Facts About Mount Mazama

Mount Mazama is a complex volcano in the state of Oregon, United States, in a segment of the Cascade Volcanic Arc and Cascade Range.

Mount Mazama is dormant, but the US Geological Survey says eruptions on a smaller scale are likely, which would pose a threat to its surroundings.

Crater Lake and Mount Mazama's remnants sustain diverse ecosystems, which are closely monitored by the National Park Service because of their remoteness and ecological importance.

Mount Mazama is in Klamath County, within the U S state of Oregon, 60 miles north of the border with California.

Furious, Llao emerged from Mazama and threw fire upon the people beneath the mountain, and Skell stood on Mount Shasta, trying to defend the people against Llao's fury.

Mount Mazama received its English name in 1896 from William G Steel, the founder of the climbing club The Mazamas, which formed at Mount Hood in 1894.

Mount Mazama sits within a region of crustal extension marked by fault zones, including north–south-trending normal faults such as the Annie Spring fault within the West Klamath Lake fault zone, which might produce damaging earthquakes.

Mount Mazama is the newest of the Quaternary calderas in the Cascade Volcanic Arc, which include the Newberry calderas and the caldera at the Medicine Lake Volcano.

Scott was the first of the composite volcanoes that created the Mount Mazama complex, formed by a quick and active cone-building phase and becoming inactive long before the most recent eruption at Mount Mazama.

Viscous eruptions of andesitic lava that reached thicknesses of several hundred feet further built up Mount Mazama's cones, creating a solid, dense interior rich with angular lava blocks.

At the time of its collapse, Mount Mazama encompassed an area of 150 square miles and represented one of the major volcanoes in the High Cascades branch of the greater Cascade Range.

Mount Mazama Scott has been heavily eroded by ice, and the Union Peak volcano now consists only of a pyramidal horn.

Mount Mazama Ash is the most widely distributed tephra layer from the late Quaternary in the United States and southwestern Canada, extending to eight states to the west and three Canadian provinces.

Mount Mazama Ash has more soda, yttrium, ytterbium, and zirconium, and less silica and lime than eruptive products from Glacier Peak, and it forms finer deposits than Glacier Peak Ash.

Mount Mazama is surrounded by monogenetic cinder cones, lava fields, and shield volcanoes made up of calc-alkaline basalt and andesite, tholeiite, and shoshonitic andesite.

Pyroclastic cones at Mount Mazama include Wizard Island, Bald Crater, Maklaks Crater and Forgotten Cone.

Mount Mazama has a few composite cones in the vicinity of the caldera.

Mount Mazama vicinity formed gradually, its earliest deposits consisting of dacite from up to 1.

Mount Mazama formed as a group of overlapping volcanic edifices, which included shield volcanoes and small composite cones.

Pumice ejected from these new fractures created rapid pyroclastic flows that coursed down all the sides of Mount Mazama, traveling over tall ridges and summits of subfeatures and extending tens of miles from their vents.

Mount Mazama is considered dormant, but it remains monitored by the United States Geological Survey Cascades Volcano Observatory.

Mount Mazama is unlikely to produce mudflows far from the caldera, though a nearby vent outside the caldera could erupt and mix with snow.

Crater Lake and the remnants of Mount Mazama can be seen from Rim Drive, a 33-mile road that surrounds the caldera, which is the only part within the Crater Lake National Park where vehicles are permitted.
