Mount Jupiter

The Brothers Wilderness is a designated wilderness area located in the Olympic National Forest on the eastern side of the Olympic Peninsula south of Buckhorn Wilderness and north of Mount Skokomish Wilderness. The wilderness area comprises 16,337 acres (6,611 ha) administered by the U.S. Forest Service. The wilderness is named after The Brothers peaks, which are the tallest in the wilderness area at 6,866 feet (2,093 m). The Duckabush River flows through the middle of the area. The area lies in the rain shadow of the Olympic Mountains, receiving about 80 inches (2,000 mm) of annual precipitation.

Mount Constance is a peak in the Olympic Mountains of Washington and the third highest in the range. It is the most visually prominent peak on Seattle's western skyline. Despite being almost as tall as the ice-clad Mount Olympus to the west, Mount Constance has little in the way of glaciers and permanent snow because the eastern, and particularly this northeastern, portion of the Olympics receives far less precipitation. However the narrow and steep Crystal Glacier still exists on the mountain's north face, shaded by the bulk of the main peak and with a small lake at its terminus. In addition, the treeline is higher here than mountains to the west, also hinting at the drier alpine conditions. By virtue of its position at the eastern edge of the Olympics, Mount Constance also enjoys spectacular vertical relief. For example, it rises over 6,900 feet (2,100 m) above the Dosewallips River to the south in only 3 horizontal miles (4.8 km). It is also only 12 miles (20 km) from the tidewater of Hood Canal. The summit of Mount Constance lies on the boundary between Olympic National Park and Buckhorn Wilderness. The Constance massif includes Mount Constance, Inner Constance, the twin peaks of Warrior to the north, as well as numerous subsidiary summits on rocky southern ridges enclosing the cirque basin that contains Lake Constance.

The Brothers are a pair of prominent peaks in the Olympic Mountains which are located in the Pacific Northwest, near Hood Canal in Washington state on the boundary between Olympic National Park and The Brothers Wilderness. The south peak, rising to 6,842 feet (2,085 m), is 192 feet (59 m) higher than the north peak. No official trails approach the summit, but the south peak is considered a non-technical climb. The Brothers' distinctive double summit is clearly recognizable from Seattle. In 1856, surveyor George Davidson named these mountains in honor of two brothers of Ellinor Fauntleroy, his future wife. He called the southern peak Mount Edward and northern peak Mount Arthur. A suggestion in late 1968 to rename the mountains "The Brothers Kennedy" in honor of John F. Kennedy and Robert F. Kennedy was not approved by the U.S. Board on Geographic Names.

Warrior Peak is a 7,320+ ft (2,230+ m) double summit mountain located in Olympic National Park and Jefferson County of Washington state. Warrior is the 11th-highest peak in the Olympic Mountains. The southeast summit is the slightly higher of the two summits, the northwest peak is estimated at 7,285 feet elevation. Precipitation runoff from the west side of the mountain drains into Home Creek, a tributary of the Dungeness River, whereas the east side drains into Tunnel Creek which is a tributary of the Big Quilcene River. Warrior Peak is easy to identify from Seattle, since it appears as the first prominent peak immediately north of Mount Constance, which is the dominant peak on the skyline. Warrior's nearest higher peak is Mount Constance, 0.8 mi (1.3 km) to the south-southeast. The first ascent of the mountain was made in 1945 by Fred Beckey, who solo climbed both summits, and named the mountain.

Inner Constance is a summit of the Olympic Mountains and is located in Jefferson County of Washington state. It is located near the eastern edge of Olympic National Park on the Olympic Peninsula. At 7,670 feet (2,338 m), Inner Constance is the fifth-highest peak of the Olympic Mountains, after Mount Olympus, Mount Deception, Mount Constance, and Mount Johnson. Its nearest higher neighbor is Mount Constance, 0.9 mi (1.4 km) to the east. Within this nearly mile-wide separation resides a deep glacially carved canyon called "Avalanche Canyon". Precipitation runoff on the north side of the peak drains into tributaries of the Dungeness River, whereas the south side drains into tributaries of the Dosewallips River.

Hamma Hamma Balds is a Washington state Natural Area Preserve. It is located in the eastern foothills of the Olympic Mountains in Mason County, above the Hamma Hamma River and adjacent to Olympic National Forest. The term "balds" refers to rocky outcroppings in the heavy forest. The preserve totals 957 acres (387 ha).The preserve was created in the 2008 fiscal year through intra-agency land exchanges between various trusts.

Triton Cove State Park is a public recreation covering 30 acres (12 ha) on Triton Cove at the southeastern corner of Jefferson County, Washington. The state park has 555 feet (169 m) of saltwater shoreline on Hood Canal with facilities for picnicking, docking, diving, fishing, crabbing, and shellfish harvesting.

Mount Worthington is a 6,938-foot (2,115-metre) elevation double-summit mountain located in the eastern Olympic Mountains in Jefferson County of Washington state. It is set within Buckhorn Wilderness, on land managed by the Olympic National Forest. The nearest neighbor is Iron Mountain, 0.76 mi (1.22 km) to the southwest, and the nearest higher peak is Buckhorn Mountain, 1.3 mi (2.1 km) to the southwest. Precipitation runoff from Mount Worthington drains south into the Big Quilcene River, or north into Copper Creek which is a tributary of the Dungeness River. This mountain was first known as Copper Peak, but was renamed by Jack Christensen for the William J. Worthington family, pioneers of nearby Quilcene. Copper was mined in the Tubal Cain mine at the northern base of this mountain in the early 1900s. In the same vicinity of the abandoned mine are the remains of a modified B-17 plane that crashed on January 19, 1952, when returning from a search-and-rescue mission.

Welch Peaks is a 6,110-foot (1,862-metre) mountain in the eastern Olympic Mountains in Jefferson County of Washington state, United States. It is set within Buckhorn Wilderness, on land managed by the Olympic National Forest. The nearest higher neighbor is Mount Townsend, 1.2 mi (1.9 km) to the north, and Mount Worthington rises 2.1 mi (3.4 km) to the southwest. Precipitation runoff from Welch Peaks drains into tributaries of the Big Quilcene River, and Silver Creek which is a tributary of the Dungeness River. Topographic relief is significant as the summit rises 3,100 feet (945 m) above Townsend Creek in approximately one mile. The mountain's toponym was officially adopted in 1963 by the U.S. Board on Geographic Names.

The Duckabush River is located in the Olympic Peninsula in Washington, United States. It rises near Mount Duckabush and Mount Steel in the Olympic Mountains within the Olympic National Park and drains to Hood Canal, an arm of Puget Sound. The name "Duckabush" comes from the Twana placename /dəxʷyabús/, meaning "place of the crooked-jaw salmon".

Brinnon is a census-designated place (CDP) in Jefferson County, Washington, United States. The population was 797 at the 2010 census. The community is named for Ewell P. Brinnon, who in 1860 took a donation land claim at the mouth of the Duckabush River. Its known landmarks include Dosewallips State Park and Black Point Marina. Camp Parsons, founded in 1919 and the oldest Boy Scout camp west of the Mississippi River, sits just outside the north end of the CDP.

The Maple Fire was a wildfire on Jefferson Ridge in the Olympic Mountains, approximately 23 miles north of Shelton, Washington in the United States. The fire was caused by illegal logging activities, and the resulting criminal trial was the first time that tree DNA has ever been used in a federal trial in the United States.
