Goat Island Mountain

The Wonderland Trail is an approximately 93-mile (150 km) hiking trail that circumnavigates Mount Rainier in Mount Rainier National Park, Washington, United States. The trail goes over many ridges of Mount Rainier for a cumulative 22,000 feet (6,700 m) of elevation gain. The trail was built in 1915. In 1981, it was designated a National Recreation Trail. An estimated 200 to 250 people a year complete the entire trail with several thousand others doing shorter sections of it. The average time taken to complete the entire trip is 10 to 14 days.

Panhandle Gap is a high pass in the U.S. state of Washington, on a ridge to the east of Mount Rainier, lying near the low point between Little Tahoma Peak and the Cowlitz Chimneys. The hike to the gap along the Wonderland Trail, which can be joined 0.1 miles (0.16 km) from Fryingpan Creek Trailhead on Sunrise Road, has been described as "possibly the best day hike" in Mount Rainier National Park; it is 10.6 miles (17.1 km) roundtrip with 3,000 feet (910 m) of elevation gain. The hike is one of the most popular in the park, and can be crowded between late July and September, and it can be difficult to find parking at the trailhead. It has been rated both easy and strenuous. After Summerland—a campsite on a knob about 4 miles (6.4 km) from the trailhead and 1.3 miles (2.1 km) below Panhandle Gap—the trail can be hard to follow, crossing Fryingpan Creek can be hazardous, and in winter and spring there can also be avalanche risk approaching the gap. At around 6,750 feet (2,060 m), the gap is the highest point on the Wonderland Trail encircling the mountain. South of the gap, the Wonderland Trail continues towards Indian Bar and Box Canyon, as the terrain drops off into Ohanapecosh Park, which drains into the Ohanapecosh River. The most popular climbing routes to Banshee Peak and the Cowlitz Chimneys arrive via Panhandle Gap, and while Banshee is a walk-up, the Middle Cowlitz Chimney can be climbed using a Class 2 scrambling route and the Main Chimney is Class 3. On a clear day, Mount Adams is visible from Panhandle Gap, but Mount Rainier itself is largely blocked by the ridge to the west. Some through-hikers deviate to the Eastside Trail, an alternate route to avoid snow and potentially dangerous conditions around the gap. Panhandle Gap is above the tree line and the terrain largely consists of rock and ice past Summerland. The rock around the gap—partly consisting of hypersthene hornblende dacite that may have formed by Tatoosh intrusion as well as andesite—is more red than that found a short distance to the north, closer to Summerland. Snow often covers the trail around the gap into late summer. Species found at the gap include horned lark, ptarmigan, mountain goats, Smelowskia, and Tolmie's saxifrage.

The Sunrise Comfort Station (S-310) is a comfort station in Mount Rainier National Park, Washington, USA. Built around 1930, the building was designed by Thomas Chalmers Vint of the National Park Service in association with landscape architect E.A. Davidson. The structure was part of a planned ensemble at what was then called Yakima Park, high on the northern flank of Mount Rainier. Similar structures may be found at the Ohanapecosh, Longmire and White River campgrounds in the park. The low building is framed in peeled logs on a stone foundation, set into a hillside and surrounded by native landscaping. The "comfort station", otherwise known as a public toilet, was placed on the National Register of Historic Places on March 13, 1991. It is part of the Mount Rainier National Historic Landmark District, which encompasses the entire park and which recognizes the park's inventory of Park Service-designed rustic architecture. Another comfort station (S-005) situated between the Yakima Park Stockade Group and the Sunrise Lodge is not part of that district but contributes to the Sunrise Historic District instead. S-310 does not.

The Yakima Park Stockade Group, also known as North and South Blockhouses and Stockade at Sunrise, is a building complex consisting of four log buildings at the Sunrise Visitors Center area in the northeast part of Mount Rainier National Park. The complex is architecturally significant as a particularly fine example of rustic frontier log architecture. The first of the blockhouses and the stockade were built in 1930, while the second blockhouse followed in 1943. It was declared a National Historic Landmark in 1987. It is in turn part of the Mount Rainier National Historic Landmark District, which encompasses the entire park and which recognizes the park's inventory of Park Service-designed rustic architecture.

The Sunrise Historic District, also known as the community of Sunrise, Washington, is located at approximately 6,400 feet (2,000 m) on a ridge overlooking the northeast side of Mount Rainier in Mount Rainier National Park. The district comprises seven individual structures designed in accordance with the principles of the National Park Service Rustic style. The area is inhabited and open to the public only during a brief period in the summer season.

The White River Bridge was built in 1929 in Mount Rainier National Park as part of the Yakima Park Road project. The new road was planned to open up access to the northeastern portion of the park. The bridge, spanning the White River, was built by contractor John D. Tobin of Portland, Oregon, who had previously built the Narada Falls Bridge and the Christine Falls Bridges, both listed on the National Register of Historic Places. Plans for the bridge were drawn by the National Park Service Branch of Plans and Designs in the National Park Service Rustic style, with construction supervision by NPS landscape architect Ernest A. Davidson. The three-centred arch spans 60 feet (18 m), with a stone-faced concrete structure. The bridge was placed on the National Register of Historic Places on March 13, 1991. It is part of the Mount Rainier National Historic Landmark District, which encompasses the entire park and which recognizes the park's inventory of Park Service-designed rustic architecture.

Antler Peak is a 7,017-foot (2,139-metre) summit located in Mount Rainier National Park in Pierce County of Washington state. It is part of the Sourdough Mountains, a subset of the Cascade Range. Antler Peak is situated west of Dege Peak and northeast of Sunrise Historic District, with the Sourdough Ridge Trail traversing the south slope of Antler between the two. Mount Fremont is the nearest higher peak, 1.55 mi (2.49 km) to the west. Precipitation runoff from Antler Peak drains into the White River.

Banshee Peak is a 7,420-foot (2,262-metre) mountain summit located in Mount Rainier National Park in Pierce County of Washington state, US. As part of the Cascade Range, Banshee Peak is situated west of the Cowlitz Chimneys and east of Panhandle Gap, with the Sarvant Glacier set below its north cliff. Precipitation runoff from Banshee Peak drains into tributaries of the White River and the Cowlitz River. Banshee Peak is a high remnant of bedded Ohanapecosh Formation lava flows. Access is from Panhandle Gap via the Wonderland Trail. The broad summit has alpine tundra similar to that found on Burroughs Mountain. The Sunrise Historic District provides a viewpoint from which to see Banshee Peak when weather permits. The road to Sunrise is only open seasonally in the summer due to closure from winter snowpack.

Mount Fremont is a 7,214-foot-elevation (2,199 m) mountain summit located in Mount Rainier National Park in Pierce County of Washington state. Mount Fremont is a minor peak at the southwest corner of the Sourdough Mountains which are a subset of the Cascade Range. It also the juncture for a small ridge of peaks of similar size running to the northeast. Mount Fremont is situated northwest of the Sunrise Historic District, with a popular trail leading to the Mount Fremont Fire Lookout. However, this trail does not reach the true summit which is 0.25 mi (0.40 km) north of Frozen Lake. Peak 7317, also known as Mount Fremont North, located 0.31 mi (0.50 km) west-northwest along the ridge is its nearest higher neighbor. Access is limited by snowpack closing the Sunrise Road much of the year. July, August, and September are typically the months when the Sunrise Road is seasonally open for vehicle traffic. Precipitation runoff from Mount Fremont drains into the White River.

McNeeley Peak is a 6,786-foot-elevation (2,068 m) summit located in Mount Rainier National Park in Pierce County of Washington state. It is part of the Sourdough Mountains, a subset of the Cascade Range. McNeeley Peak is situated north of the Sunrise Historic District, east of Mount Fremont, and northwest of Antler Peak. The peak was named in 1932 for Edwin J. McNeeley (born 1858), a prominent Tacoma businessman. Access is limited by snow closing the Sunrise Road much of the year. July, August, and September are typically the months when the Sunrise Road is seasonally open for vehicle traffic. Precipitation runoff from McNeeley Peak drains into the White River.

Dege Peak is a 7,009-foot (2,136 m) summit located in Pierce County of Washington state. It is part of the Sourdough Mountains in Mount Rainier National Park. It was named in 1932 for James Henry Dege (born 1868), a prominent Tacoma businessman and Captain of the First Regiment National Guard of Washington. The peak is a popular hiking destination with views of the Emmons Glacier, Winthrop Glacier, Inter Glacier, Fryingpan Glacier, Little Tahoma Peak, and views in all directions because the trail is above tree line. The trail starts at the Sunrise Historic District. Access is limited by snowpack closing the Sunrise Road much of the year. July, August, and September are the months when the Sunrise Road is seasonally open for vehicle traffic. Antler Peak is the nearest higher neighbor, 1.03 mi (1.66 km) to the west. Precipitation runoff from Dege Peak drains into the White River.

The Sourdough Mountains, also called Sourdough Ridge, is a mountain ridge on the northeast side of Mount Rainier in Mount Rainier National Park, Washington, United States. The range forms an L-shape, starting at Mount Fremont, running east to Dege Peak, turning north to Slide Mountain. The ridge is a popular hiking destination, due to the excellent view of Mount Rainier and its proximity to roads and the Sunrise Visitor Center.
