About the Marys Peak Group

Wilderness Act Poster

Join us on November 9!

The Marys Peak Group operates from Corvallis, Oregon and serves the region of Benton, Lincoln, Linn, Marion, and Polk counties — from the Yachats to Otis on the Pacific coast to the high Cascades. We take our name from the nearby Marys Peak, the highest mountain in the coast range.

Within our region lie portions of the Siuslaw and Willamette National Forests. We are blessed with three National Wildlife Refuges — William L. Finley, Basket Slough, and Ankeny, and six wilderness areas -- Drift Creek, Menagerie, Middle Santiam, Opal Creek, Bull of the woods, Mt. Jefferson and Mt. Washington. Significant other areas within our range are managed by the Bureau of Land Management.

Major rivers include the Willamette, Santiam, Siletz, Yaquina, and Alsea with their many tributaries. The two major communities within the region are Corvallis and the state capitol Salem.
