Mount Rainier (14,411 feet) is the highest peak in Washington, and 5th highest in the conterminous USA. There are many great routes on Rainier, and any ascent is a true classic. The most commonly-climbed route is the Disappointment Cleaver from the Paradise parking lot, via Camp Muir and Ingraham Glacier. The route requires glacier travel and around 9,000 feet of altitude gain.

Mount Olympus is the highest peak in the Olympic Mountain Range of Western Washington. Despite it's relatively low altitude [7965 feet], Olympus is heavily glaciated due to it's close proximity to the Pacific Ocean. Precipitation in the nearby Hoh Rain Forest ranges from 140 to 167 inches--12 to 14 feet--every year, which translates into a lot of snowfall on Olympus, thus maintaining large accumulations of ice such as the Blue Glacier. Located in the center of Olympic National Park, Mount Olympus is also quite remote, and requires a 1 day hike just to reach it's base.
