Unicorn Peak (Olympic Mountains)

Hurricane Hill is a 5,757-foot (1,755 m) mountain summit located within Olympic National Park in Clallam County of Washington state. It is part of the Olympic Mountains and is situated at the western end of Hurricane Ridge within the Daniel J. Evans Wilderness. Hurricane Hill is nine miles south-southwest of Port Angeles and two miles northwest of the park's Hurricane Ridge Visitor Center. Precipitation runoff from the mountain drains to the Elwha River via various tributaries. Topographic relief is significant as the southwest aspect rises 5,100 feet (1,600 m) above the Elwha Valley in three miles.

Olympic National Park is a United States national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west-side temperate rainforest, and the forests of the drier east side. Within the park there are three distinct ecosystems, including subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast.President Theodore Roosevelt originally designated the park as Mount Olympus National Monument on March 2, 1909. The monument was re-designated a national park by Congress and President Franklin D. Roosevelt on June 29, 1938. In 1976, Olympic National Park was designated by UNESCO as an International Biosphere Reserve, and in 1981 as a World Heritage Site. In 1988, Congress designated 95 percent of the park (1,370 square miles (3,500 km2)) as the Olympic Wilderness, which was renamed Daniel J. Evans Wilderness in honor of Governor and U.S. Senator Daniel J. Evans in 2017. During his tenure in the Senate, Evans co-sponsored the 1988 bill that created the state's wilderness areas. It is the largest wilderness area in Washington.

The Hurricane Ridge Ski and Snowboard Area is a small ski area in the northwest United States, located on the Olympic Peninsula of Washington. It is within Olympic National Park, seventeen miles (27 km) south of Port Angeles. Hurricane Ridge is one of only three lift-serviced ski areas operating in a U.S. National Park (Badger Pass in Yosemite National Park, and Boston Mills/Brandywine Ski Resort in Cuyahoga Valley National Park are the others). It is the westernmost ski area in the continental United States. During months when snow is present, the 17-mile road leading to Hurricane Ridge is prone to avalanches due to high speed wind conditions. Park rangers may close the road leading to the snow park for a whole day.

Mount Angeles is located just south of Port Angeles, Washington in the Olympic National Park. It is the highest peak in the Hurricane Ridge area. The summit, which offers panoramic views of the Strait of Juan de Fuca and many of the peaks of the interior Olympic Mountains can be climbed from the Klahane Ridge trail.The southeast side of Mount Angeles drains into Morse Creek, thence into the Strait of Juan de Fuca a couple of miles east of Port Angeles. The northeast side of Mount Angeles drains into Ennis Creek, thence into Port Angeles Harbor. The north and west sides of Mount Angeles drain into the South Branch of Little River, thence into the Juan de Fuca Strait via the Elwha River, whose mouth is located in the Lower Elwha Indian Reservation, a few miles west of Port Angeles.

The Elwha Campground Community Kitchen was built in Olympic National Park to serve the Altair Campground. It is an open octagonal shelter built in 1935 by the Civilian Conservation Corps personnel from the Elwha River Camp in the National Park Service Rustic style. The peeled log structure is capped with a cedar shake roof, enclosing a cooking fireplace and chimney. The Elwha and Altair Campground Community Kitchens are the only such structures remaining in Olympic National Park.The Elwha Ranger Station and the Altair Campground Community Kitchen are located nearby on the banks of the Elwha. The lower portions of the log posts have deteriorated and have been replaced with concrete piers.The kitchen structure was listed on National Register of Historic Places on July 13, 2007.By 2014 the Elwha Dam and all other dams along the Elwha River were removed. When the river flooded in November 2015, both Altair and Elwha Campgrounds were severely damaged by water. National Park Service has no plans to restore the two campgrounds. The actual state of buildings in the two areas is not clear.

The Elwha Ranger Station is a historic district in Olympic National Park, originally built in the 1930s for the U.S. Forest Service. The complex of fourteen buildings is divided in two by Olympic Hotsprings Road. To the east lie the ranger station and three residences, with nine maintenance buildings on the west side of the road. The complex was turned over to the National Park Service in 1940 when the land was added to Olympic National Park from Olympic National Forest. Construction is typical of USFS practice, and reflects the Forest Service's preference of the time for bungalow and American Craftsman style architecture.The Elwha area was designated as one of fifteen areas in Olympic National Forest to be used for public recreation. The "Cleator Plan," named after Forest Service recreation engineer Fred W. Cleator, envisioned the construction of appropriate structures to support these activities, including a ranger station. In the mid-1930s a Civilian Conservation Corps camp was established nearby, contributing labor for forest construction projects. When the area was taken over by the National Park Service in 1940 the complex continued in use virtually unchanged, retaining its Forest Service character.

The Altair Campground Community Kitchen, also known as Altaire Campground Community Kitchen, was built in Olympic National Park, Washington, United States, to serve the Altair Campground. It is an open rectangular shelter built in 1935 by the Civilian Conservation Corps personnel from the Elwha River Camp in the National Park Service Rustic style. Located near the Elwha River, the peeled log structure is capped with a cedar shake roof, enclosing a cooking fireplace and chimney. It measures about 28 feet (8.5 m) by 17 feet (5.2 m), with a stone cooking fireplace in the middle, rising through the roof. The lower portions of the log columns have been replaced with concrete piers due to deterioration, and the original peeled log railings have disappeared.The Altair and Elwha Campground Community Kitchens are the only such structures remaining in Olympic National Park. The Altair campground was named after the USS Altair, whose crew regularly used the site in the 1920s and 1930s. The kitchen structure was listed on National Register of Historic Places on July 13, 2007.By 2014 the Elwha Dam and all other dams along the Elwha River were removed. When the river flooded in November 2015, both Altair and Elwha Campgrounds were severely damaged by water. National Park Service has no plans to restore the two campgrounds. As of May 2023, rangers at Olympic National Park confirmed the Altair Kitchen was under about 9 feet of sediment, and the Elwha Kitchen is completely covered in sediment from the Elwha River.

Madison Creek Falls is located within the Olympic National Park near the Elwha River, west of Port Angeles, Washington. The falls is about 50 feet high and has a light flow in a horsetail shape. Another higher falls is located above the first, but is completely inaccessible. The paved trail to the falls is very short (less than 100 meters) and is wheelchair accessible.

The Geyser Valley trail in Olympic National Park is an area along the Elwha River between Rica Canyon and the Grand Canyon of the Elwha, where many homesteaders tried to eke out a living in the late 19th and early 20th centuries. Today, this trail allows hikers to visit several interesting sites, as well as, providing several loops of different lengths. The route begins at Whiskey Bend Trailhead, at the end of Whiskey Bend road, approximately 5 miles from the Elwha Ranger Station. It travels for about 1.3 miles along the Elwha River trail, before the first descent down approximately 400 feet to Goblins Gate at the head of Rica Canyon. The trail continues along the Elwha River through a riparian forest of bigleaf maple, red alder, black cottonwood, with Douglas fir, Western red cedar, and Grand fir. The trail passes the alder grove of Krause Bottom, where the first possible loop back up the slope heads up, and some old homesteader clearings, before arriving at Humes Ranch Cabin, approximately 3 miles from the trailhead. Humes Ranch Cabin is maintained today by the National Park Service as a historic site, and the meadows below the cabin are kept open as Humes once did. You can also see 100-year-old fruit trees in the pastures. Approximately 3/4 of a mile further, the trail climbs the eroding cliffs along the river and crosses Dodger point bridge at the mouth of the Grand Canyon of the Elwha. This marks the end of Geyser Valley, but the trail continues for 11 miles up to the summit of Dodger Point Mountain at over 5,700 ft. It is possible to begin looping back to the Elwha river trail, by slowly climbing the slope. The trail will meet the short-cut coming up from Humes Ranch Cabin and then will pass the old homestead of Michael's Cabin. The trail then heads back on a level grade back towards Whiskey Bend trailhead. Homesteaders historically reported seeing enormous numbers of salmon coming up the river each year to spawn. However, salmon have been blocked from the upper 65 miles of river habitat with the construction of the Elwha Dam in 1913. However, both the Elwha Dam and Glines Canyon Dam were removed in 2012. As part of the Elwha Ecosystem Restoration project, Chinook salmon began returning to the Geyser Valley.

Wolf Creek Falls is located in Olympic National Park in Clallam County, Washington approximately 10 miles (16 km) south west of Port Angeles, Washington. The falls is located on Wolf Creek, a tributary of the Elwha River. The falls is a tiered falls with drops totaling about 100 feet.

Glines Canyon Dam, also known as Upper Elwha Dam, built in 1927, was a 210-foot (64 m) high concrete arch dam built on the Elwha River within Olympic National Park, Clallam County, Washington. It was located 13 miles (21 km) upstream from the mouth of the Elwha River at the Strait of Juan de Fuca, and about 8 miles upriver from the Elwha Dam. It impounded Lake Mills reservoir. The dam was demolished in 2014 as part of the Elwha River ecosystem restoration project; as of 2015 it is the tallest dam ever to be intentionally breached. The Glines Canyon Dam was the largest dam removal ever.

Indian Creek is a tributary of the Elwha River located in Washington in the United States. Indian Creek flows from Lake Sutherland into the former Lake Aldwell. Historically, Indian Creek supported runs of several anadromous salmon and trout species, including all five species of Pacific Salmon. However, with construction of the Elwha Dam in 1913, fish were blocked from accessing the Pacific Ocean. While the Elwha Dam was in operation, Indian Creek sustained populations of kokanee sockeye salmon, which spawned in Lake Sutherland and migrated to Lake Aldwell to use as their ocean. It also contained stream resident coastal rainbow trout, coastal cutthroat trout, and introduced eastern brook trout. With the removal of the Elwha Dam in 2012, the native salmonids began a return to their anadromous lifestyle, with spawning activities of true anadromous Chinook salmon observed in late 2013.
