Located in the Willamette National Forest near Santiam Pass, it lies adjacent to the cinder cone Hoodoo Butte, which has a ski area.
[1] Close to Santiam Pass,[2] it forms part of the United States Geological Survey topographic map for the Three Fingered Jack volcano.
[6] In response to a new master plan at the Hoodoo Ski Bowl in 1995, the United States Forest Service released a draft environmental impact statement for the surroundings.
[10] The Oregon Department of Fish and Wildlife determined in the early 1990s that there was potential for peregrine falcon nests at Hayrick Butte, though it was considered low-quality habitat because of its lack of suitable ledges and high amounts of human disturbance.
[11] According to a 2003 paper, Hayrick Butte has a rich forest on its steep, north-facing slope with mountain hemlock and mature fir trees[12] at an elevation of 5,090 feet (1,550 m).
)[16] The nearby lava dome and tuya (subglacial volcano) Hogg Rock shows more similarity to the basaltic andesite deposits at North Sister, which are poorly enriched in incompatible elements.
[17] The part of the High Cascades that extends south from Mount Jefferson to Santiam Pass includes shield volcanoes, lava domes, and cinder cones.
[19] Like Hogg Rock, Hayrick Butte is an andesite lava dome[20] with a flat top, suggesting that it is also a tuya, or a subglacial volcano.
[21] Both Hayrick Butte and Hogg Rock produced porphyritic andesite lava with plagioclase and orthopyroxene and trace levels of phenocrysts with olivine.
[29] A backcountry, snowshoeing trail runs for 4 miles (6.4 km) from the Hoodoo ski area,[30] rising about 200 feet (61 m) in elevation over its course.
[26] Markian Hawryluk of The Bulletin in Bend described Hayrick as "antisocial" compared to the "family-friendly ski area" of Hoodoo Butte,[26] citing its 700-foot (210 m) tall, nearly vertical walls.
