Tamanos Mountain

Barrier Peak is a small 6,521-foot (1,988-metre) summit located in Mount Rainier National Park in Pierce County of Washington state. It is part of the Cascade Range and is situated west of Cayuse Pass, 0.53 mile west-northwest of Buell Peak, and 0.4 mile south-southwest of Governors Ridge, which is its nearest higher peak. Precipitation runoff from Barrier Peak drains into tributaries of the White River and Cowlitz River. The normal climbing access is from the Owyhigh Lakes Trail. The peak was so named because it served as a barrier between the Cayuse Pass region and the rest of Mount Rainier National Park.

Governors Ridge is located in Mount Rainier National Park in Pierce County of Washington state. It is part of the Cascade Range and is situated west of Cayuse Pass and 1.09 mile east of Tamanos Mountain, which is the nearest higher peak. Precipitation runoff from Governors Ridge drains into tributaries of the White River and Cowlitz River. The toponym honors all the governors who have served the state of Washington. The highest rocky crag on the ridge is known as Governors Peak. There is also a 40-foot leaning spire known as Governors Needle, and Barrier Peak is at the southern culmination of the ridge. The normal climbing access is from the Owyhigh Lakes Trail.

Cowlitz Chimneys are a group of four rhyolite towers located in Mount Rainier National Park in Pierce County of Washington state. As part of the Cascade Range, the Cowlitz Chimneys are situated southwest of Tamanos Mountain and east of Banshee Peak, all of which are visible from the Sunrise Historic District. The Sarvant Glacier is set on the north aspect of these remnants of a volcanic plug. Cowlitz is the name of several geographical features in Mount Rainier National Park, as well as the state of Washington. The name appeared as early as the Lewis and Clark journals of 1805 when it was written as "Cowliskee" and has the Chinook Jargon meaning of "capturing the medicine spirit".

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.

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.

Buell Peak is a small 5,756 ft (1,754 m) summit located in Mount Rainier National Park in Pierce County of Washington state. It is part of the Cascade Range and is situated 1.5 miles southwest of Cayuse Pass and 0.53 mile east-southeast of Barrier Peak, which is the nearest higher peak. Precipitation runoff from Buell Peak drains into tributaries of the Cowlitz River. The normal climbing access is from the Owyhigh Lakes Trail. The peak's toponym honors John Latimore Buell who arrived in Orting, Washington, in 1890 and went into the hardware business.

Double Peak is a 6,199-foot (1,889 m) double summit mountain located in Mount Rainier National Park in Pierce County of Washington state. Part of the Cascade Range, it is situated northwest of Shriner Peak, south of Governors Ridge, and southeast of the Cowlitz Chimneys. Precipitation runoff from Double Peak drains into the Ohanapecosh River which is a tributary of the Cowlitz River. Topographic relief is significant as the summit rises 3,400 feet (1,036 meters) above the Ohanapecosh in one mile (1.6 km). The mountain's descriptive toponym was officially adopted in 1932 by the United States Board on Geographic Names.

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.

Sydney Falls, more commonly called Kotsuck Creek Falls or Kotsuck Falls, is a waterfall in the Mount Rainier National Park in the U.S. state of Washington. The falls is formed as Kotsuck Creek, a tributary of the Cowlitz River, thunders 200 feet (61 m) into a steep and rugged canyon in a plume 75 feet (23 m) wide. The falls start with a small tier of 30 feet (9.1 m), then splits into three streams and plunges over a sheer cliff face, joining at the bottom. The name of the falls comes from a 1912 article that mentions that "Sydney Falls is along the Wonderland Trail". The name "Kotsuck" comes from a Chinook Indian word meaning "middle". However, the name "Kotsuck Creek Falls" may be inaccurate, as the names of Kotsuck Creek and Chinook Creek may have been switched at some time in the past.

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 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.

The White River Mess Hall and Dormitory is the only remaining Civilian Conservation Corps camp structure remaining in Mount Rainier National Park, Washington, United States. The wood-framed building was built in 1933, and comprising 2,185 square feet (203.0 m2), originally containing a kitchen dining room, living room, two bathrooms, a bedroom and a bunkroom, as well as a service porch. The building no longer serves as a residence and is used for storage. It is located at the White River entrance to the park, part of a complex of service buildings. The mess hall was listed on the National Register of Historic Places on March 13, 1991. It is included in the White River Entrance Historic District. 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.
