Mineral Mountain (Mount Rainier National Park)

Old Desolate is a 7,137-foot (2,175 m) multi-summit, ridge-like mountain located in Mount Rainier National Park, in Pierce County of Washington state. It is part of the Cascade Range, and lies five miles (8.0 km) due north of the summit of Mount Rainier. The Wonderland Trail provides an approach to this mountain, and the summit offers views of Sluiskin Mountain and Mount Rainier. Burroughs Mountain is the nearest higher neighbor, 2.37 mi (3.81 km) to the southeast. Precipitation runoff from Old Desolate drains east into the West Fork White River, or west into the Carbon River.

Willis Wall is the name given to the prominent headwall of the Carbon Glacier's eastern cirque on Mount Rainier in the state of Washington. The 3,600 feet (1,097 m) foot wall of volcanic rock on Mount Rainier's north face was named in honor of geological engineer, Bailey Willis, who helped create the first trail to the Carbon Glacier in 1881 and was also influential in securing the passage of the bill that created Mount Rainier National Park in 1899. At over a mile wide, the Carbon Glacier cirque is the largest in the Cascade Mountains. The wall itself is composed of ledges of lava, ash, consolidated breccias, and rock impregnated ice.

Crescent Mountain, a ridge-like peak standing at 6,715 ft (2,047 m), is located in north-central Mount Rainier National Park, in Pierce County of Washington state. It is part of the Cascade Range, and lies 6.6 mi (10.6 km) due north of the summit of Mount Rainier. Sluiskin Mountain is its nearest higher neighbor, 0.85 mi (1.37 km) to the east. Precipitation runoff from Crescent Mountain drains west into tributaries of the Carbon River.

Sluiskin Mountain is a prominent pair of summits located in Mount Rainier National Park in Pierce County of Washington state. It is situated northwest of Burroughs Mountain and is part of the Cascade Range. The higher rocky peak is known as The Chief (7026 ft), and the second peak to the west is known as The Squaw (6960+ ft). West of The Squaw are pinnacles called The Papooses. Sluiskin was the native American guide who assisted with the first successful ascent of Mount Rainier by Hazard Stevens and P. B. Van Trump in 1870. Sluiskin Falls within the park also honors him.

Burroughs Mountain is a mountain in Pierce County, Washington, United States.

Mount Ruth is an 8,690-foot summit located within Mount Rainier National Park in Pierce County of Washington state. Part of the Cascade Range, Mount Ruth is situated between the Emmons Glacier and the Inter Glacier. Access is via the Glacier Basin Trail. The name of the peak honors Ruth Knapp, daughter of the prospector who built Knapp's Cabin in Glacier Basin below the peak. Precipitation runoff from Mount Ruth drains into the White River.

Skyscraper Mountain is a 7,078-foot-elevation (2,157-meter) summit in Pierce County of Washington state.

Emmons Glacier is on the northeast flank of Mount Rainier, in Washington. At 4.3 sq mi (11 km2), it has the largest surface area of any glacier in the contiguous United States. The glacier was named after the geologist Samuel Franklin Emmons after his involvement in a survey of Mount Rainier in 1870. Starting at an elevation of over 13,800 ft (4,200 m), the Emmons glacier flows down eastward. Near the Disappointment Cleaver at 12,200 ft (3,700 m), the Emmons is joined by the Ingraham Glacier flowing to the south. The glaciers flow together and remain connected until they split up upon reaching the wedge of Little Tahoma Peak. As the Emmons flows northeast, the massive glacier descends until it reaches its rocky lower terminus at about 5,100 ft (1,600 m) in elevation. In the 1930s, the glacier was found to be receding quickly. In 1963, however, a rock fall from Little Tahoma Peak covered the lower glacier with rock debris. The debris cover insulated the ice from melting. As a result of decreased melting, the glacier advanced rapidly in the early 1980s. That advance was continuing by 1992, but at a slower rate; ice beneath the rock debris was melting irregularly and forming a vast hummocky area. By 2003, the glacier was again retreating. "In the past few decades the glaciers [in the American West] have been receding, continuing a trend from the Little Ice Age." Emmons Glacier is often used as a route (the Columbia Crest route) to climb to the summit of Mount Rainier. There is a Ranger Station at Camp Schurman that was established on the edge of the Steamboat Prow.

Little Tahoma Peak, also called Little Tahoma, is a satellite peak of Mount Rainier in Pierce County, Washington and in Mount Rainier National Park. It is quite noticeable from Seattle over 60 miles (97 km) away. Little Tahoma Peak is a volcanic remnant. It was part of a larger Mount Rainier which has eroded. The rock is quite unstable and in 1963 a large avalanche originating below it covered the lower section of Emmons Glacier with rock debris. The Fryingpan Glacier and Whitman Glacier are located just to the east of the peak. Little Tahoma Peak can most easily be accessed from Summerland, an alpine meadow area in Mount Rainier National Park. The first recorded ascent was on August 29, 1894, by JB Flett and Henry H. Garrison who climbed from Summerland using the east shoulder. If considered on its own, Little Tahoma would be the third-highest peak in Washington.

On June 21, 1981, an avalanche near Ingraham Glacier, in Mount Rainier, struck a climb party attempting to reach the summit of Mount Rainier. Out of the 29 members, 11 were killed, making it the deadliest avalanche in the history of the mountain.

Ingraham Glacier is on the south-eastern flank of Mount Rainier, in the U.S. state of Washington. The glacier is named for the Mount Rainier enthusiast Edward Sturgis Ingraham. From the summit ice cap, Ingraham Glacier flows east between Gibraltar Rock, (12,660 ft (3,860 m)), and Disappointment Cleaver and south of Little Tahoma Peak (11,138 ft (3,395 m)), which divides it from the much larger Emmons Glacier to the north. Descending southeast, it approaches the east flank of Cowlitz Glacier and the two glaciers nearly join at 6,700 ft (2,000 m). Meltwater from the glacier drains into the Cowlitz River.

The Mount Fremont Fire Lookout is a fire lookout in the northern region of Mount Rainier National Park at an elevation above 7,000 feet (2,100 m), the highest in the park. One of four fire lookouts remaining in the park, the lookout is used for visitor services during summer weekends. The building is about 14 by 14 feet (4.3 by 4.3 m), and was designed by the National Park Service Branch of Plans and designs under the supervision of Acting Chief Architect Edwin A. Nickel. It was built in 1933. The two-story structure features a balconied lookout on the second level, with storage on the ground level. Cables secured to deadmen keep the lookout from blowing over. The Park Service was assisted during construction by the Emergency Conservation Works Association. The lookout was extensively damaged in a 2006 storm, along with the park's Gobbler's Knob Fire Lookout. They've since been repaired. The lookout 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.
