John Wayne Pioneer Trail (West) Professional Review and Guide
"The John Wayne Pioneer Trail crosses most of Washington State. The developed portion lies within the Iron Horse State Park. It parallels I–90 from Cedar Falls, near North Bend, to Kittitas, then drops south through army land to end on the edge of the magnificent Columbia River.
The trail passes through various climatic zones. West of the Cascades are the wet and green Cascade foothills. East of the mountains you’ll find glacial valleys with pine and fir trees and ranchland. As you continue east, the landscape changes to sagebrush desert, arid scrublands, and the irrigated farmlands of the Columbia Basin. East of Thorp the trail is unshaded and dry, hot in summer and cold in winter. Bear, bobcats, cougars, rattlesnakes, eagles, ospreys, rodents, rabbits, and butterflies inhabit different parts of the trail. Surface: Compacted ballast, gravel, and sand; the trail is 16 to 20 feet wide. The section from Cedar Falls to Easton has the most compacted surface. Location: Cedar Falls to the Columbia River."
