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.
The Catlin Gabel tubes lie among cinder cones and lava flows from the Pliocene to Pleistocene, and they are the oldest known lava tubes in Oregon, older than the Holocene. [83] The tubes were produced by a small vent at the southern end of the northern segment of the field, [ 84 ] extending 2.5 miles (4.0 km) from its base to the south and then ...

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]
They reach thicknesses of greater than 6.6 feet (2 m) as far as 5.6 miles (9 km) from the Sand Mountain cinder cone and greater than 3.3 feet (1 m) up to 7.5 miles (12 km) from the cinder cone. [32] Microfractures within Sand Mountain clastic rock [ 36 ] along with the blocky, equant shapes and density of sideromelane and tachylite clastic rock ...

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.
