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.

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).

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.

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.

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.

Woden is a 6,038-foot (1,840-metre) mountain summit located within Olympic National Park in Jefferson County of Washington state. Its nearest higher neighbor is Mount Tom, 3 mi (4.8 km) to the north-northwest, and Mount Olympus rises 3.8 mi (6.1 km) to the north-northeast. Woden is the highest point in The Valhallas, a sub-range south of Mount Olympus. Precipitation runoff from the mountain drains into tributaries of the South Fork Hoh River and Queets River. The Geri-Freki Glacier, which descends north from Woden. is the only glacier in The Valhallas.

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.

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.

Hubert Glacier is located on the south side of Mount Olympus in the Olympic Mountains and Olympic National Park. Due to its southern orientation, the glacier is smaller than those on the north side of Mount Olympus, such as Blue Glacier. Named for Anna Hubert, the only female member of the first ascent of Mount Olympus, the Hubert Glacier occupies a cirque at the bottom of the headwall, with one branch extending to the south up the mountainside. Starting from this highpoint of the glacier at 6,500 feet (2,000 m), it flows northward until it meets the glacial ice located in the cirque at about 5,600 ft (1,700 m). The glacier changes direction and flows west to its terminus at about 5,000 ft (1,500 m).

Sol Duc Hot Springs is a resort located in Olympic National Park, Washington state, that is best known for its soaking pools, hot tubs, and a swimming pool that are heated with the nearby hot springs. The resort is situated in a valley carved by the Sol Duc River. The springs, known to local Native American tribes for their therapeutic value, first came to the attention of settlers in the 1880s. An elaborate resort opened up in 1912, and was characterized as "the most noted pleasure and health resort on the Pacific Coast" until it burned down in 1916. The resort was rebuilt on a much less grand scale in the 1920s, and was operated into the 1970s until it ran into trouble with its thermal spring in the 1970s. These problems were overcome, and the resort was rebuilt in the 1980s. It continues to operate until this day, attracting thousands of visitors a year. Also located in the area is the undeveloped Olympic Hot Springs.

Blue Glacier is a large glacier located to the north of Mount Olympus in the Olympic Mountains of Washington. The glacier covers an area of 1.7 sq mi (4.4 km2) and contains 580,000,000 cu ft (16,000,000 m3) of ice and snow in spite of its low terminus elevation. The glacier length has decreased from about 3.4 mi (5.5 km) in 1800 to 2.7 mi (4.3 km) in the year 2000. Just in the period from 1995 and 2006, Blue Glacier retreated 325 ft (99 m). Blue Glacier is also thinning as it retreats and between 1987 and 2009 the glacier lost 178 ft (54 m) of its depth near its terminus and between 32 and 48 ft (9.8 and 14.6 m) in the uppermost sections of the glacier known as the accumulation zone.
