Introduction
Departing from the Portneuf Valley at 4,460 feet, your journey to Chelan Falls (elevation 1,050 feet) drops nearly a vertical mile in highway terms. The 670-mile route bypasses major metropolises, offering a cross-section of the Pacific Northwest's geological basement and agricultural heartland.
On I-84 westbound, the first named pass is Blue Mountain Summit (elev. 4,920 ft), a Columbia River Basalt Group remnant that erupts with wildflowers in June. You'll cross the Snake River near Glenns Ferry, where the Oregon Trail's Three Island Crossing State Park marks a critical ford used by 19th-century emigrants.
Before you leave Pocatello, top off at the Costco on Yellowstone Ave (regular unleaded available) and note the Idaho State Veterans Cemetery—a landmark that signals the city's southern exit.
