Yakima Canyon Rim (Skyline) Professional Review and Guide
"This 9.2-mile round-trip day hike or overnighter follows a portion of the Yakima Canyon Rim Scenic Trail over open, sage-covered hills above the spectacular 2,000-foot-deep canyon of the Yakima River. Views are expansive in all directions, sun is plentiful, and you’ll find a profusion of wildflowers carpeting the hillsides in spring.
The Columbia Basin, a basalt-shrouded landscape between the Rocky Mountains and the Cascade Range, is not simply a large, featureless depression as the name might suggest.Along the western margin of the basin lies a region of great ridges (anticlines) separated by deep troughs (synclines).The Horse Heaven Hills, Saddle Mountains,Yakima Ridge, and Frenchman Hills, among others, dominate the landscape here, reaching heights of 4,500 feet. Far below, the Columbia and Yakima Rivers have cut down through the uplifting land, creating impressive canyons."
