Hayrick Butte

Hayrick Butte is a flat-topped volcanic mountain near Santiam Pass in Oregon’s Cascades, rising about 700 feet above the surrounding terrain to roughly 5,482 feet. Geologically, it is a tuya, formed when lava erupted beneath ice, creating its broad summit plateau and steep, near-vertical sides. Later glaciation further shaped the butte and helped preserve the summit crater of neighboring Hoodoo Butte by blocking erosive ice. Its north slope supports subalpine forest, and although peregrine falcon nesting was once considered possible, the habitat was judged poor. Today it remains a prominent but relatively quiet landmark used for climbing and winter recreation.
