Mount Scott is a volcanic cinder cone with its summit in Clackamas County, Oregon.The summit rises to an elevation of 1,091 feet (333 m). [1] It is part of the Boring Lava Field, [3] a zone of ancient volcanic activity in the area around Portland, and was named for Harvey W.

The Mount Washington Wilderness includes a number of cinder cones, typically with elevations between 150 and 300 feet (46 and 91 m). Composed of gray to red cinder, they also have scoria and welded spatter. [24] Major cinder cones in the wilderness include Belknap Crater, Twin Craters, Scott Mountain, and the Sand Mountain craters. [25]
Three other cinder cones from this field also lie within the city of Portland: Rocky Butte, Powell Butte, and Kelly Butte. Portland is one of six cities in the United States to have an extinct volcano (Mount Tabor) within its boundaries. Bend is the only other city in Oregon with a volcano within its city limits, with Pilot Butte.
Pilot Butte is a lava dome that was created from an extinct volcano located in Bend, Oregon. It is a cinder cone butte which rises nearly 500 feet (150 m) above the surrounding plains. Bend is one of six cities in the United States to have a volcano within its boundaries.
Hoodoo Butte is a cinder cone butte in the Cascade Range of northern Oregon, located near Santiam Pass. Immediately to the east lies Hayrick Butte, a prime example of a tuya; the two mountains' names were likely mistaken for each other, but stuck with them over time. The area has been subjected to a number of historic fires.
Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
