Cone-building eruptions took place within short periods of time.
[22], The Klamath Native Americans of the area believed that Mount Mazama was inhabited by Llao, their "Chief of the Below World. This eruption, the largest known within the Cascade Volcanic Arc in a million years, destroyed Mazama's summit, reducing its approximate 12,000-foot (3,700 m) height by about 1 mile (1,600 m). Financed by a successful gold miner named John Wesley Hillman, Skeeters led a team with ten other Oregonians to find the mine.
[30] Hillman Peak was the youngest composite cone in the Mazama eruptive center, forming about 70,000 years ago. Olive-sided flycatchers and chipping sparrows are common during the spring and summer seasons, while yellow-rumped warblers, pine siskins, and Cassin's finches can frequently be seen during spring, summer, and fall. [1] Even so, highly consequential eruptions at Mazama seem unlikely in the near future. [5] Whenever eruptions took place in the presence of ice, lava was chilled by glaciers, creating glassy talus deposits. Extending from the eastern half of Mazama and to the southeast lies a volcanic field consisting of rhyodacitic lava domes and lava flows between 700,000 and 600,000 years old, which encompasses an area of more than 140 square miles (350 km2). The lake shows convective mixing that cycles every three years as thermal fluid moves into the lake through its floor, creating thermal springs that formed silica spires with heights up to 33 feet (10 m).

Lake levels rose while the Wizard Island landform inside the crater was forming. [7] The Global Volcanism Program currently lists its elevation at 8,157 feet (2,486 m),[1] while the Geographic Names Information System provides an elevation of 6,174 feet (1,882 m). [14], Though it now has dimensions of 5.0 by 6.2 miles (8 by 10 km) and a width of 5.0 to 6.2 miles (8 to 10 km), scientists think the original collapse diameter was 3.1 miles (5 km). [58][63] Glacier Peak Ash has not been found in deposits less than 10,000 years old, and nearly all human artifacts have been found above its deposits, except for a site at Birch Creek where non diagnostic artifacts were discovered beneath Glacier Peak Ash. [54] At the time of its collapse, Mount Mazama encompassed an area of 150 square miles (400 km2) and represented one of the major volcanoes in the High Cascades branch of the greater Cascade Range. [66], Pyroclastic cones at Mazama include Wizard Island, Bald Crater, Maklaks Crater (also known as Diller Cone) and Forgotten Cone.
At least three pika populations in Oregon have disappeared within the past few decades. [91] Aerosol from the eruption traveled as far as Greenland,[59] falling for as long as six years. [18] The southern region of the park supports ponderosa pine forests, and for elevations from 5,000 to 7,000 feet (1,500 to 2,100 m), mixed coniferous, fir, and hemlock forests are common.
