Olympic National Park 4K drive (Hoh Rain Forest) - Washington

Driving out of the Hoh Rainforest in Olympic National Park on June 8th, 2021.

The Hoh Rain Forest, pronounced "Hoe", earns its name from the ever-flowing Hoh River that carves its way from Mount Olympus towards the Pacific Coast. However, where the name originates, is up for debate. The word "Hoh" undoubtedly comes from Native American languages; possibly the Quileute word "Ohalet" which means "fast moving water" or "snow water." Since the river itself forms from glacial runoff, that origin seems straightfoward. Other explanations state that the Quinault word "Qu," meaning "boundary," could be the root of the name as a river as massive as the Hoh certainly forms a formidable boundary across the landscape. A third consideration claims that the word "Hoh" translates to "man with quarreling wives." What the actual history behind the name is appears to be lost to time.

Regardless of the name, there's no question as to the allure that draws visitors back to the rainforest year after year. Throughout the winter season, rain falls frequently in the Hoh Rain Forest, contributing to the yearly average of 140 inches (3.55 meters) of precipitation each year. The result is a lush, green canopy of both coniferous and deciduous species. Mosses and ferns that blanket the surfaces add another dimension to the enchantment of the rainforest.

The Hoh Rain Forest is located in the stretch of the Pacific Northwest rainforest which once spanned the Pacific coast from southeastern Alaska to the central coast of California. The Hoh is one of the finest remaining examples of temperate rainforest in the United States and is one of the park's most popular destinations.

The Hoh lies on the west side of Olympic National Park, about a two-hour drive from Port Angeles and under an hour from Forks. The Hoh Rain Forest is accessed by the Upper Hoh Road, off of Highway 101.

Hoh Rainforest is one of the largest temperate rainforests in the U.S., located on the Olympic Peninsula in western Washington state. 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.

The dominant species in the rainforest are Sitka spruce (Picea sitchensis) and western hemlock (Tsuga heterophylla); some grow to tremendous size, reaching 95 meters (312 ft) in height and 7 m (23 ft) in diameter. Coast Douglas-fir (Pseudotsuga menziesii var. menziesii), western red cedar (Thuja plicata), bigleaf maple (Acer macrophyllum), red alder (Alnus rubra), vine maple (Acer circinatum), and black cottonwood (Populus trichocarpa) are also found throughout the forest.

Many unique mosses and lichens are also present in the rainforest, such as lettuce lichen (Lobaria oregana), which "requires the cool, moist conditions found under the canopy of old-growth forests" and is consumed by deer, elk, and other animals.

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.

Many native fauna also make the Hoh Rainforest their home, including the Pacific tree frog (Pseudacris regilla), northern spotted owl (Strix occidentalis caurina), bobcat (Lynx rufus), cougar (Puma concolor cougar), raccoon (Procyon lotor), Olympic black bear (Ursus americanus altifrontalis), Roosevelt elk (Cervus canadensis roosevelti), and black-tailed deer (Odocoileus columbianus).

The area is also home to the banana slug (Ariolimax columbianus), which has recently been threatened by the encroachment of a new species of slug, the black slug (Arion ater), an invasive species from Northern Europe.
