The Tipsoo Lake Comfort Station was designed by the National Park Service Branch of Plans and Designs in the National Park Service Rustic style and built in Mount Rainier National Park by the Civilian Conservation Corps in 1934. The design was supervised by Park Service Chief Architect Thomas Chalmers Vint, and is similar to the Sunrise Comfort Station in the central portion of the park. Located near the park's northern entrance, two comfort station were planned to be part of a developed area in the vicinity of Tipsoo and Chinook Pass, which was never developed beyond the toilet facilities and an entrance arch. One of these survives and remains in use. The public toilet facility features rough stonework to window sill level, with a framed wall above and a log-framed roof with cedar shingles. The Tipsoo Lake Comfort Station 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.

Cayuse Pass (el. 4,675 ft (1,425 m)) is a mountain pass in the Cascade Mountains in the state of Washington. The pass is about 41 mi (66 km) southeast of Enumclaw on State Route 410, about 1+1⁄4 miles (2.0 km) west of SR410's Chinook Pass. The intersection with State Route 123 is at the pass. The pass carries State Route 410 and State Route 123 between Packwood and Enumclaw. Because of the high elevation, Cayuse Pass is usually closed in November due to very heavy snow and significant avalanche danger. It usually opens in mid-May, and is not uncommon to have a snow depth at the summit of up to 15 ft (4.6 m). As part of the All-American Road program, Route 410 through Cayuse Pass has been designated by the U.S. government as the Chinook Scenic Byway.

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.
