The known human history of the Grand Canyon area stretches back 10,500 years, when the first evidence of human presence in the area is found. Native Americans have inhabited the Grand Canyon and the area now covered by Grand Canyon National Park for at least the last 4,000 of those years. Ancestral Pueblo peoples, first as the Basketmaker culture and later as the more familiar Pueblo people, developed from the Desert Culture as they became less nomadic and more dependent on agriculture. A similar culture, the Cochimi also lived in the canyon area. Drought in the late 13th century likely caused both groups to move on. Other people followed, including the Paiute, Cerbat, and the Navajo, only to be later forced onto reservations by the United States Government.
Ratón Pass is a 7,834 ft (2,388 m) elevation mountain pass on the Colorado–New Mexico border in the western United States. It is located on the eastern side of the Sangre de Cristo Mountains between Trinidad, Colorado and Raton, New Mexico, approximately 180 miles (290 km) northeast of Santa Fe. Ratón is Spanish for "mouse". The pass crosses the line of volcanic mesas that extends east from the Sangre de Cristo Mountains along the state line, and furnishes the most direct land route between the valley of the Arkansas River to the north and the upper valley of the Canadian River, leading toward Santa Fe, to the south. The pass now carries Interstate 25 and railroad tracks.
The Cumbres and Toltec Scenic Railroad, often abbreviated as the C&TSRR, is a 3 ft narrow-gauge heritage railroad that operates on 64 miles (103 km) of track between Antonito, Colorado, and Chama, New Mexico, in the United States. The railroad is named for two geographical features along the route: the 10,015-foot (3,053 m)-high Cumbres Pass and the Toltec Gorge. Originally part of the Denver and Rio Grande Western Railroad's narrow-gauge network, the line has been jointly owned by the states of Colorado and New Mexico since 1970. Today, the C&TSRR is one of only two remaining parts of the former D&RGW narrow-gauge network, the other being the Durango and Silverton Narrow Gauge Railroad (D&SNG), which runs between the communities of Durango and Silverton, Colorado. The railroad has a total of ten narrow-gauge steam locomotives and two narrow-gauge diesel locomotives on its current roster. The railroad also operates two smaller former D&RGW steam locomotives, Nos. 315 and 168, for special events and excursions.

The Denis Julien Inscription is an incised carving on a rock face in a side canyon of the Green River north of Canyonlands National Park in southwestern Grand County, Utah, United States. The site is about 750 feet (230 m) to the east of the Green River in Hell Roaring Canyon, at the top of a talus slope. The inscription was left by trapper Denis Julien in 1836, when he was one of the few Europeans in southern Utah. The panel reads:

Denis Julien was an American fur trapper of French-Canadian Huguenot origin best known for his activity in the southwestern United States in the 1830s and 1840s, at a time when he was one of the few people of European descent in the area. He is principally remembered for his habit of leaving carved inscriptions on rock faces in Utah and Colorado during his travels. At least eight such markings have been positively attributed to him, four of which are listed on the National Register of Historic Places.

Mantle's Cave is a cliff alcove in Dinosaur National Monument in Moffat County, Colorado. Located in the Castle Park region of the park, it is the largest rock shelter in the area. It was discovered before 1921 by local ranchers, Mr. and Mrs. Charles Mantle. Mrs. Mantle is reported to have done some excavation of the site, followed up by the Penrose-Taylor expedition of 1933 from Colorado College and the Fountain Valley School, which designated the site "Cave One." The site is a significant resource for the Fremont culture and is among the best resources in northwestern Colorado. Excavations in the 1930s and 1940s yielded significant material on the Fremont people and their relationship to the later Ancestral Puebloans.
Rio Grande Southern Railroad (RGS), Motor No. 2 is a gasoline engine-powered narrow gauge railroad motorcar. It was converted on August 12, 1931 from a 1927 Buick Master Six 4-door sedan in a conversion known as a Galloping Goose. The Buick was cut behind the rear doorpost and extended with sheet metal 18 inches (46 cm) to form an enlarged passenger compartment. With no functional use, the steering column was removed. The couch from the RGS office become the back seat as it is shown being requisitioned for Goose No. 2 on the statement covering construction. The front axle was removed and replaced with a swiveling, two-axle lightweight railroad truck with 16 in (41 cm)-diameter wheels that carried and guided the front of the Goose. Ahead of the front truck the pilot is attached to the frame. There were two small pivoted scrapers attached to the rear of the pilot to keep small objects on the track from derailing the lightweight front truck. During the winter season a small snowplow was attached to the front of the pilot.
