Olympus Guard Station

Bogachiel Peak is a 5,478-foot (1,670 m) peak in the Olympic Mountains of Washington, U.S.. It is located in Olympic National Park, and is a high point on the High Divide separating the Hoh River and Sol Duc River valleys, and forming the southern rim of Seven Lakes Basin. The peak is situated at the headwaters of the Bogachiel River. The name "Bogachiel" is a corruption of the Quileute words bo qwa tcheel el, or /boqʷač'íʔl/, from /bó:q'ʷa/, "muddy", and /číʔlowa/, "water", meaning "gets riley [turbid] after a rain", "muddy waters", or, less likely, "big river".

Seven Lakes Basin is a formerly-glaciated mountain lake basin located at the headwaters of the Sol Duc River in Olympic National Park. A hiking trail to the basin is 19 miles (31 km) round trip with about 4,000 feet (1,200 m) of elevation gain. The loop trail starts by following the Sol Duc River near Sol Duc Hot Springs, traversing south past Sol Duc Falls before beginning a rapid elevation gain to eventually arrive at the High Divide separating the Hoh River valley from the Sol Duc valley, with views across the Hoh Valley to Mt. Olympus to the south. While the basin itself in late summer is a barren rocky landscape, it is surrounded by high elevation old-growth forest and alpine meadows lush with wildflowers and wild blueberries. Despite the name, Seven Lakes Basin, there are actually eight small lakes and numerous tiny ponds in the area. These lakes are Sol Duc, Long, Lunch, Morgenroth, No Name, Clear, Round, and Lake No. 8. The largest lake is Sol Duc and the smallest is Morgenroth. Other subalpine lakes encountered along this loop trail below the High Divide which are not considered part of "seven lakes" include Heart Lake and Deer Lake. Heart Lake gets its name from its distinctive heart-like shape. Black Bear, marmots, black-tailed deer and Olympic Elk are common in this area. Fishing is a popular activity in the area, although there are no fish in Heart Lake and several of the other smaller lakes in the basin.

White Glacier is located on the north slopes of Mount Tom in the Olympic Mountains and Olympic National Park in the U.S. state of Washington. The main portion of the glacier heads at around 7,000 and 6,400 feet (2,100 and 2,000 m) in a cirque just under the summit rocks, while the westernmost section of White Glacier is partially separated from the rest of the glacier by several small ridges of rock and flows straight north. The principle portion of the glacier flows north as well, with a glacier toe descending to around 4,800 feet (1,500 m) where the toe turns northeast to its terminus at 4,400 feet (1,300 m). Steep ridges of rock separate an eastern portion of the White Glacier from the Blue Glacier cirque on adjacent Mount Olympus, to the east. Like the other glaciers on Mount Olympus, White Glacier has retreated significantly since its Little Ice Age maximum. At its greatest extent in the early 19th century, it was connected with Blue Glacier and Black Glacier. During the next ~150 years it retreated rapidly and by 1952 it had retreat 10,500 feet (3,200 m). It then advanced a small distance between 1955 and 1980 due to a cooler and wetter climate. The glacier began to retreat again in the 1980s and retreated ~1000 ft (300 m) from its position in 1980 to 2006.

The Olympic Mountains are a mountain range on the Olympic Peninsula of the Pacific Northwest of the United States. The mountains, part of the Pacific Coast Ranges, are not especially high – Mount Olympus is the highest summit at 7,980 ft (2,432 m); however, the eastern slopes rise precipitously out of Puget Sound from sea level, and the western slopes are separated from the Pacific Ocean by the low-lying 20 to 35 km (12 to 22 mi) wide Pacific Ocean coastal plain. These densely forested western slopes are the wettest place in the 48 contiguous states. Most of the mountains are protected within the bounds of Olympic National Park and adjoining segments of the Olympic National Forest. The mountains are located in western Washington in the United States, spread out across four counties: Clallam, Grays Harbor, Jefferson and Mason. Physiographically, they are a section of the larger Pacific Border province, which is in turn a part of the larger Pacific Mountain System.

Mount Appleton is a 6,000+ ft (1,830+ m) double summit mountain located in the Olympic Mountains, in Clallam County of Washington state. It is set within Olympic National Park and is situated northwest of Appleton Pass. Its nearest higher peak is South Appleton (6100+ ft), 0.33 mi (0.53 km) to the south. Precipitation runoff from Mount Appleton drains into the Sol Duc River, and Boulder Creek which is a tributary of the Elwha River, thence into the Strait of Juan de Fuca.

Mount Tom is a remote 7,076-foot (2,157-metre) mountain summit located within Olympic National Park in Jefferson County of Washington state. Its nearest higher neighbor is Mount Olympus, 1.76 mi (2.83 km) to the east. Due to heavy winter snowfalls, Mount Tom supports the massive White Glacier on its northeast slope, despite its modest elevation. This glacier is the westernmost glacier in the contiguous states, and the summit is the westernmost peak higher than 7000+ feet elevation. Precipitation runoff from the mountain drains into tributaries of the Hoh River.

Cat Peak is a 5,940-foot (1,810-metre) mountain summit within Olympic National Park in Clallam County of Washington state.

Mount Olympus, at 7,980 feet (2,430 m), is the tallest and most prominent mountain in the Olympic Mountains of western Washington state, US. Located on the Olympic Peninsula, it is also a central feature of Olympic National Park. Mount Olympus is the highest summit of the Olympic Mountains; however, peaks such as Mount Constance and The Brothers, on the eastern margin of the range, are better known, being visible from the Seattle metropolitan area.

The Canyon Creek Shelter, also known as the Sol Duc Falls Shelter, is a rustic trail shelter in Olympic National Park. It is the last remaining trail shelter built in the park by the Civilian Conservation Corps (CCC) from Camp Elwha. The shelter was built in 1939, shortly after Olympic National Park was established from the U.S. Forest Service-administered Mount Olympus National Monument. Two similar shelters were built at Moose Lake and Hoh Lake, neither of which survive. The one-story log structure is T-shaped, with a projecting front porch crowned by a small cupola. The shelter is open to the front porch.The shelter was listed on the National Register of Historic Places on July 13, 2007.

Boulder Peak is a peak located in Washington state, in Olympic National Park. The mountain is accessible by using the Olympic Hot Springs Trail and the Appleton Pass trail. These two trails lead to Boulder Lake located at the base of Boulder Mountain where there is a campground. There are no official trails to the top of the peak, but one can find a beaten path and with a fair amount of scrambling can reach the summit. The summit offers views of the surrounding Olympic Mountains and various lakes. The round trip from trail head to summit is approximately 13 miles.

Boulder Lake is located in the Olympic National Park in Washington. It is accessible by the Olympic Hot Springs Trail and the Appleton Pass trail. The hike is about 12 miles (19 km) round trip and has about a 2,500-foot (760 m) elevation gain. At the lake there are a few camp sites and a bear wire to hang food. The lake lies at the base of Boulder Peak.

One Square Inch of Silence is a noise control project symbolized by a small red stone symbolically placed in Hoh Rainforest at Olympic National Park in 2005 by author and sound recording specialist Gordon Hempton. The stone's location has been called "the quietest place in the United States". According to commercial pilot Philip Greenspun, some airlines have voluntarily rerouted flights to avoid inducing noise pollution at the square inch. Hempton has formed a foundation to prevent jet aircraft noise in Olympic National Park and other parks.Hempton's works, including One Square Inch of Silence, were covered in the 2010 documentary Soundtracker which debuted at the Sedona Film Festival.
