Physical map of Washington

Washington is bounded by the Pacific Ocean to the west, Oregon to the south (the Columbia River forming most of this border), Idaho to the east and British Columbia, Canada to the north.
Washington is a land of contrasts. The deep forests of the Olympic Peninsula are among the rainiest places in the world and the only rainforests (such as the Hoh Rain Forest) in the continental United States, but the flat semi-desert that lies east of the Cascade Range stretches for long distances without a single tree. Snow-covered peaks tower above the foothills and lowlands around them. Mount Rainier, the highest mountain in the state, appears to "float" on the horizon southeast of Seattle and Tacoma on clear days. The eastern side of the state can be divided into two regions: the Okanogan Highlands and the Columbia River Basin.
