- National Park,
Mild winters, cool summers and up to 12 feet of annual precipitation produce the giant conifers that dominate this rain forest, one of the most spectacular examples of temperate rain forest in the world.
Bigleaf maple and vine maple host an abundance of epiphytes (plants growing upon other plants) that give the rain forest its characteristic look and ethereal quality. A plethora of mosses, ferns and plants compete for space on the forest floor; grazing elk keep the understory open. Dead and downed trees decay slowly and support new life as ‘nurselogs.' The eternal cycle of life and death is strikingly apparent in this magnificent forest community.
The Hoh River
The 50-mile long wild Hoh River is born high on glacier-capped Mount Olympus and descends 7,000 feet to the Pacific Ocean, fed by snowmelt and rain along the way. The glaciers of its birth grind rock into glacial flour, coloring the river a milky, slate blue. On its descent the river meanders, creating gravel bars and cutting into the lush rain forest along its banks.
Immense fallen conifers are swept downriver and create logjams and quiet pools for salmon. Their spawned-out carcasses feed dozens of aquatic and forest animals and fertilize the soil, bringing riches from the ocean to the forest. In turn, the forest lends stability to the river by preventing massive sediment flushing. Mountain, river, forest, ocean––each part of this ecosystem depends on the other, a tapestry woven together as one naturally functioning unit
For Future Generation
The first 12 miles of the Upper Hoh Road outside the park is a mosaic of second growth, third growth and pastures. Logging, clearing for homesteads and market hunting of elk changed the look of this valley. Even 100 years ago, there was concern that humans were altering the landscape on a grand scale.
Olympic National Park was created in 1938 to preserve “the finest example of primeval forest…and provide permanent protection for the herds of native Roosevelt elk.” Thus, the Hoh Valley from the park boundary to Mount Olympus looks much like it has for 5,000 years. About 400 of the park’s estimated 4-5,000 elk live in the Hoh Valley today.
In a world of diminishing resources, this forest has become valuable to people for many reasons. The beauty and tranquility found here is one of this country’s rare treasures. It is a gift of ocean, rain, river, mountains, and the wisdom of past generations, ours to cherish and care for in turn.
