Marys Peak anchors this corner of the Coast Range, where high ridges and steep drainages define the landscape of western Benton County. The Marys River and its tributaries, including Clark Creek and Norton Creek, carve through the timbered uplands near the small communities of Blodgett and Alder. Transportation follows the contours of the land, with routes like Marys Peak Rd and Skyline Dr providing access to high-elevation points such as the Marys Peak Observation Point.
