Hoh Rainforest is one of the largest temperate rainforests in the U.S., located on the Olympic Peninsula in western Washington state.[1] It includes 24 miles (39 km) of low elevation forest 394 to 2,493 feet (120 to 760 m) along the Hoh River. The Hoh River valley was formed thousands of years ago by glaciers.
Within Olympic National Park, the forest is protected from commercial exploitation. Between the park boundary and the Pacific Ocean, 48 km (30 mi) of river, much of the forest has been logged within the last century, although many pockets of forest remain.
