Sol Duc Hot Springs

The Eagle Ranger Station, also known as the Eagle Guard Station and presently known as the Sol Duc Ranger Station, is a complex of three buildings built in the 1930s in what would become Olympic National Park. The primary structures were built by the U.S. Forest Service in what was at the time the Olympic National Forest., While the main residence was built by the USFS, the generating plant and landscaping were built by the National Park Service using labor provided by the Civilian Conservation Corps.The ranger station residence was built in 1936, using wood-frame construction. The 1+1⁄2-story house is a simple gabled structure with an asymmetrically placed porch framed in timbers. The residence is clad in large singles. A large window on the front elevation is divided in the middle by a heavy mullion, with transoms over both units and twelve lights divided by small muntins. Other windows are six-over-six double-hung sashes Rustic shutters with pine-tree cutouts frame the windows, echoing the USFS pine tree symbol. The house is consistent with the Forest Service's standard construction style, incorporating features of bungalow and rustic construction.The garage was also built in 1936. The one-story structure is of wood-frame construction and is clad in shingles The 1940 generator house was built by the CCC. The one-story frame structure is capped with a hipped roof and topped by a cupola. It lies about 50 feet (15 m) to the east of the residence.The Eagle Ranger Station was added to the National Register of Historic Places on July 13, 2007.

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.

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.

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.

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.

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".

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.

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.

The Olympus Guard Station near Port Angeles, Washington was built in 1930s. It was built by the U.S. Forest Service and was designed by architects of the U.S. Forest Service. It is located about nine miles backcountry, within what is now the National Park Service-administered Olympic National Park.It was listed on the National Register of Historic Places in 2007. It has also been known as OGS and as Olympus Guard Station Historic District. The NRHP listing included five contributing structures and one contributing building on 2 acres (0.81 ha).

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.

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

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.
