Mount Chiquita

Ypsilon Mountain, elevation 13,520 ft (4,121 m), is in the Mummy Range of Rocky Mountain National Park in northern Colorado. The mountain, along with Mount Chiquita, is most easily accessed from a trailhead on Fall River Road to the south.

Mount Chapin is a 12,454-foot-elevation (3,796-meter) mountain summit located in Rocky Mountain National Park, in Larimer County, of Colorado, United States. It is situated 11 miles west-northwest of the community of Estes Park, one mile east of Chapin Pass, and six miles east of the Continental Divide. Mount Chapin is part of the Mummy Range which is a subset of the Rocky Mountains. Topographic relief is significant as the south aspect rises 2,700 feet (820 meters) above Fall River in less than one mile. Neighbors include Mount Chiquita and Ypsilon Mountain to the immediate northeast, and the park's Alpine Visitor Center is three miles to the west.

The Old Fall River Road, sometimes referred to as "The Old Road" by park staff in Rocky Mountain National Park, was the first automobile road to penetrate the interior of the park. The road linked the east side of the park near Estes Park with Grand Lake on the west side. Work began in 1913 but was interrupted in 1914 by World War I with final work being completed between 1918 and 1920. The narrow road was partly replaced by Trail Ridge Road in 1932, which incorporated sections of the Fall River Road. The road runs westward from Sheep Lakes to the Alpine Visitor Center. A rockslide closed the road in 1953 and it was not re-opened until 1968 when the National Park Service cleared the rocks and paved the lower third of the route. Both the one-way Old Fall River Road and the paved Trail Ridge Road are maintained and open to motor vehicles from Memorial Day weekend through the first major autumn snowstorm. Both roads are also open to bicycles from April 1 through November 30, but are not patrolled in the pre- and post-season times. Old Fall River Road may be closed for a time to all uses for maintenance.

Chasm Falls is a waterfall with a 25-foot (7.6 m) drop located on the Fall River in Rocky Mountain National Park.

Fairchild Mountain is a high mountain summit in the Mummy Range of the Rocky Mountains of North America. The 13,508-foot (4,117 m) thirteener is located in the Rocky Mountain National Park Wilderness, 9.6 miles (15.5 km) northwest (bearing 311°) of the Town of Estes Park in Larimer County, Colorado, United States.

The Willow Park Stable in Rocky Mountain National Park was designed by National Park Service landscape architect Daniel Ray Hull and built in 1926. The National Park Service Rustic style stables and the nearby Willow Park Patrol Cabin were built to house crews maintaining the Fall River Road.

The Willow Park Patrol Cabin, also known as the Willow Park Ranger Station and the Willow Park Cook and Mess Hall, was built in Rocky Mountain National Park in 1923 to the design of members of the National Park Service Landscape Engineering Division under the supervision of Daniel Ray Hull. The cabin is an early example of the National Park Service Rustic style that was gaining favor with the Park Service. The cabin, along with the Willow Park Stable, originally accommodated maintenance crews on the Fall River Road.

The Beatrice Willard Alpine Tundra Research Plots were established in 1959 along Trail Ridge Road in Rocky Mountain National Park, Colorado, above the treeline in an alpine tundra habitat. The plots were used by Beatrice Willard of the Institute of Arctic and Alpine Research at the University of Colorado from 1959 to about 1999 in a long-term study of the alpine ecosystem. Willard's dissertation and updates, as well as her book Land Above the Trees: A Guide to American Alpine Tundra were highly influential in studies of alpine and tundra ecology. Her recommendations were used by the National Park Service in its management of the high alpine areas of the park. Willard's work continued after she moved on to other work, and for the last twenty years she made informal visits to the plots. There are two plots. The Rock Cut Plot is at an elevation of 12,110 feet (3,690 m) near the Rock Cut parking area. The research plot is 5 feet (1.5 m) by 20 feet (6.1 m), within a 50-foot (15 m) by 40-foot (12 m) enclosure. A 3 feet (0.91 m) fence keeps park visitors from disturbing the plot, and is marked by an explanatory sign. An old footpath runs through the plot, and was monitored to establish rates of regrowth on the tundra. The Forest Canyon Plot is at an elevation of 11,716 feet (3,571 m), measuring only 10 feet (3.0 m) square, originally protected by a metal fence. It is close to the Forest Canyon Overlook. The plots were placed on the National Register of Historic Places on October 25, 2007.

The Timberline Cabin in Rocky Mountain National Park, Colorado, USA was built in 1925 to house workers on the Fall River Road. The National Park Service rustic style cabin was designed by the National Park Service's Landscape Engineering Division under the direction of Thomas Chalmers Vint. The cabin was later used as a patrol cabin and as a caretaker's residence. The one-story cabin stood above the timberline. It was built of concrete with a stone veneer. The roof framing used peeled logs with an asphalt roll roofing weather surface, protected by a log lattice on top. The cabin had two doors and ten windows, and measured about 32.33 feet (9.85 m) by 16.33 feet (4.98 m). The Timberline Cabin was placed on the National Register of Historic Places on January 29, 1988. It has since been demolished.

The Fall River Pump House and Catchment Basin in Rocky Mountain National Park, Colorado, are utility structures which treat water for the Fall River Pass Museum and the Alpine Visitor Center.

Horseshoe Park is a flat at 8,524 feet (2,598 m) in elevation in Larimer County, Colorado. It is within the Rocky Mountain National Park, which lies between Estes Park to the east and Grand Lake, Colorado on the west. Horseshoe Park is home to bighorn sheep, elk and other wildlife, and it is a wetland sanctuary for a wide variety of birds. Recreational activities include picnicking, hiking, cross-country skiing and snowshoeing. Roaring River, Lawn Lake and Crystal Lake are located here. An inn was operated in the area for almost 25 years, until 1931, when the inn was purchased by the federal government. After the inn was removed, the land returned to its natural state. From 1933 to 1942, the Civilian Conservation Corps operated a camp in Horseshoe Park, and the men removed beetle-infested trees, built and improved trails and campgrounds, and other projects.

The Roaring River is a 6.5-mile-long (10.5 km) tributary of the Fall River in Larimer County, Colorado. The river's source is Crystal Lake in the Mummy Range of Rocky Mountain National Park The river flows through Lawn Lake before a confluence with the Fall River in Horseshoe Park. The collapse of the Lawn Lake Dam in 1982 scoured the river's channel and deposited an alluvial fan of debris in Horseshoe Park.
