The Mount Evans Wilderness is a U.S. Wilderness Area in Arapaho National Forest and Pike National Forest about 30 miles (48 km) west of Denver, Colorado. The wilderness area is named after Mount Blue Sky's former name, Mount Evans

The Mount Evans Scenic Byway is a 49-mile (79 km) National Forest Scenic Byway and Colorado Scenic and Historic Byway located in Clear Creek and Jefferson counties, Colorado, United States. The byway ascends to 14,140 feet (4,310 m) of elevation near the 14,271-foot (4,350 m) summit of Mount Blue Sky, making it the highest paved road in North America (beating the 14,115-foot (4,302 m) Pikes Peak Highway by only 25 feet (8 m).) The byway visits Echo Lake Park, the Mount Goliath Natural Area, the Dos Chappell Nature Center, and Summit Lake Park on its way to the summit. A fee is charged to travel State Highway 5 to the summit and vehicles over 30 feet (9.1 m) long are not allowed, although they are allowed on State Highway 103 which reaches its highest elevation of 11,020 feet (3,359 m) at Juniper Pass. The byway connects to the Lariat Loop Scenic and Historic Byway at Bergen Park.

Mount Blue Sky (formerly Mount Evans) is the highest peak in the Mount Evans Wilderness in the Front Range of the Rocky Mountains of North America. The prominent 14,271-foot (4,350 m) fourteener is located 13.4 miles (21.6 km) southwest by south (bearing 214°) of Idaho Springs in Clear Creek County, Colorado, United States, on the drainage divide between Arapaho National Forest and Pike National Forest.The peak is one of the characteristic Front Range peaks, dominating the western skyline of the Great Plains along with Pikes Peak, Longs Peak, and nearby Mount Bierstadt. Mount Blue Sky can be seen from over 100 miles (160 km) to the east, and many miles in other directions. Mount Blue Sky dominates the Denver metropolitan area skyline, rising over 9,000 feet (2,700 m) above the area. Mount Blue Sky can be seen from points south of Castle Rock, up to (65 miles (105 km) south) and as far north as Fort Collins (95 miles (153 km) north), and from areas near Limon (105 miles (169 km) east). Due to the negative associations of Territorial Governor John Evans with the Sand Creek Massacre, changing the name of Mount Evans was discussed over several years. On September 15, 2023, the United States Board on Geographic Names officially changed the mountain's name to Mount Blue Sky.

Meyer–Womble Observatory (MWO) is an astronomical observatory owned and operated by the University of Denver. It is located near the summit of Mount Blue Sky in the Arapaho National Forest approximately 60 kilometers (37 mi) west of Denver, Colorado (USA). At an elevation of 4,326 meters (14,193 ft), it is the third-highest optical/infrared observatory in the world, and was the highest until the Indian Astronomical Observatory opened in 2001.Through a gift of $3.8 million from the estate of William Womble, construction of the facility began in 1995 and was completed in 1996. Eric Meyer, M.D., an anesthesiologist who designed the dual-aperture 0.72 m (28 in) f/21 Ritchey-Chretien telescope, and his wife, Barbara, donated $1 million and brought the optical components personally from Chicago. The optical/infrared telescopes saw first light in August 1997.During the 2011–12 winter, the dome over the telescope was damaged by high winds, allowing snow to enter the observing area. The telescope was secured in early April 2012 by a mountaineer who hiked to the summit. A complete inspection of the damage did not take place until the road to the summit opened in May. During the following summer, the remains of the old dome were demolished and a new dome was fabricated. Installation of the new structure occurred on October 20, 2012.

Summit Lake Park is a park located along Mount Evans Scenic Byway about 64 miles (100 km) west of Denver, Colorado. The park is 160 acres (0.65 km²) in size and contains alpine tundra. Land to the east of the lake is in a state of permafrost which helps to prevent drainage of the area. During the summer, the park is filled with wildflowers, some of which have not been found anywhere else outside of the Arctic Circle. The park is named after Summit Lake, the headwaters of Bear Creek.

The Sawtooth is a jagged arête joining Mount Bierstadt to (eventually) Mount Blue Sky in the Front Range of central Colorado. The three points along this arête resemble the teeth of a saw, leading to its name. The southeast wall of the arête is the head of the cirque above Abyss Lake, while its northwest wall is the cirque at the head of a valley above Guanella Pass. The northeast end of the sawtooth joins directly to the shoulder of Mount Spalding, from which a second (and slightly less abrupt) arête leads southeast to Mount Blue Sky. This second arête divides the glacial valley of Abyss Lake to the southwest from the cirque of Summit Lake to the northeast.

Mount Bierstadt is a 14,065-foot-high (4,287 m) mountain summit in the Front Range of the Rocky Mountains, in the U.S. state of Colorado. The fourteener is located in the Mount Evans Wilderness of Pike National Forest, 9.4 miles (15.1 km) south by east (bearing 171°) of the Town of Georgetown in Clear Creek County. It was named in honor of Albert Bierstadt, an American landscape painter who made the first recorded summit of the mountain in 1863.

Echo Lake Park is a park located along the Mount Evans Scenic Byway about 33.5 mi (54 km) west of Denver, Colorado. The park provides a stone shelter with picnic tables and barbecue grills on one end of the lake, and the 1926 Echo Lake Lodge (gift shop and restaurant service only) and an Arapaho National Forest campground are found at the other. Access to backpacking trails, including the Chicago Lakes trail and Lincoln Lakes trail, can be found adjacent to the lake. The park is part of the Denver Mountain Parks system.

The Xcel Energy Cabin Creek Fire occurred on October 2, 2007, at Xcel Energy’s pumped storage hydroelectric plant near Georgetown, Colorado, a small town forty-five miles west of Denver. The accident killed five workers and injured three. The incident is thought to be the result of botched work by a contractor (RPI Coating) and Xcel Energy's willingness to cut costs at the expense of safety.
