Olympic National Park

Olympic National Park is a massive protected area in Washington state.

It sits on the Olympic Peninsula along the Pacific coast. The park is unique because it contains four distinct regions. These include the Pacific coastline and the high alpine areas. It also contains a west-side temperate rainforest and drier eastern forests. This variety creates three different ecosystems within one park. These are subalpine wildflower meadows, temperate forests, and the rugged Pacific coast.

The geology of the park is quite complex and fascinating. The Olympic Mountains formed through an accretionary wedge process. This happened due to the subduction zone of the Juan De Fuca Plate. This tectonic process uplifted the mountains from the ocean floor. The mountains are made of a mixture of basaltic and oceanic sedimentary rock. The park is also famous for its unique turbidites. Turbidites are sediments that travel into the ocean as suspended particles. These particles create a sedimentary layering effect on the ocean floor. Over time, these sediments compact into rock in a constant cycle.

Visitors might also notice strange rocks called tectonic mélanges. These are large rocks that are big enough to appear on maps. Some of these mélanges are as large as a house. Locals call them "smell rocks" because they have a strong petroleum odor. The coastline is also shaped by natural forces like the Hoh River. The river discharges large amounts of naturally eroded timber and drift. This material moves north and enriches the beaches. This driftwood creates a commanding visual and biological presence on the shore.

The mountains contain massive, ancient glaciers that sit on high ridgelines. However, these glaciers are changing due to climate change. The number of glaciers fell from 266 in 1982 to 184 by 2009. Mount Olympus is the most prominent peak in the western range. It is the greatest non-volcanic peak in the contiguous United States outside the North Cascades. It holds several glaciers, including the Hoh Glacier. The Hoh Glacier is 3.06 miles long. In the east, the mountains are much drier. This is because of the rain shadow created by the western mountains.

The western side of the park is home to temperate rainforests. These include the Hoh and Quinault Rainforests. They receive over 140 inches of annual precipitation. This makes it perhaps the wettest area in the continental United States. Unlike tropical rainforests, these are dominated by coniferous trees. You will see Sitka Spruce, Western Hemlock, Coast Douglas-fir, and Western redcedar.

Moss often coats the bark and hangs from branches in green tendrils. The eastern side is much drier and lacks Sitka Spruce. The trees there are generally smaller and the undergrowth is less dense.

Because the park is on an isolated peninsula, it has many endemic species. Endemic species are plants or animals found only in one specific place. Examples include the Olympic Marmot, Piper's bellflower, and Flett's violet. The park also provides habitat for Roosevelt elk. These elk are native only to the Pacific Northwest coast. The park is home to sizable black bear and black-tailed deer populations.

There is also a population of about 150 cougars. Mountain goats were also introduced by accident in the 1920s. They have caused damage to the native flora. Scientists study these unique species to understand how life evolves.

Human history in the area is very long. Before European settlers arrived, Native Americans used the peninsula for fishing and hunting. They used the subalpine meadows extensively for tribal activities. Later, settlers arrived and began the timber industry in the late 19th century. This led to public dissent against logging in the 1920s. To protect the land, President Theodore Roosevelt created a monument in 1909. This was meant to protect the Roosevelt elk.

Later, President Franklin D. Roosevelt made it a national park in 1938. In 1988, Congress designated much of it as the Daniel J. Evans Wilderness. This is the largest wilderness area in Washington. Today, the park remains a vital biological reserve.
