Lewis and Clark State Park, about six miles northeast of Winlock near Mary's Corner, preserves one of Washington's last major stands of old-growth forest despite having no direct connection to the Lewis and Clark expedition. Established in 1922 on Lacamas Hill after Clark Savidge set aside the tract, it was dedicated that September as Washington's largest state park and the park system's largest old-growth tract. A 1921 resolution required it to remain a natural wooded landscape. The park later grew to 616 acres, with trails, camping, Civilian Conservation Corps structures, traces of the Oregon and Cowlitz trails, regrowing forest after the 1962 Columbus Day Storm, and even natural gas storage beneath it by 2005.
