MD_Red Peak from Madonna DomeRed Peak, 13,215 feet, from the summit of "Madonna Dome".

"Madonna Dome" sits just above Boreas Pass in the Tenmile-Mosquito Range of Colorado. "Madonna Dome" is part of the Hoosier Ridge of the Continental Divide. The standard route from Boreas Pass to the summit begins at the historic Section House, built in 1882 to house railroad workers and their families.

From the summit of "Madonna Dome", the hiker can enjoy views of other mountains including Boreas Mountain (13,082), Bald Mountain (13,679), Red Peak (13,215), Red Mountain (13,229) and the ever-graceful Mount Silverheels (13,822), as well as the “numbered peaks” of Breckenridge. On a clear day, Pikes Peak (14,115) is visible in the distance to the east. The relatively short distance to the summit (less than 2 miles from the trailhead) makes a summit hike of "Madonna Dome" a pleasurable outing for all levels of hikers.

Boreas Pass
Named for the Greek God of the North Wind, Boreas Pass (11,482 feet) is rich in mining and railroading history. The names of miners who worked the rock and the workers who built and maintained the Denver South Park & Pacific (DSP&P) paint a brilliant quilt of late 19th century United States immigration. Today, the railroad to the summit of Boreas Pass has been replaced by a gravel automobile route, and the area is popular among tourists and outdoorspeople of many stripes.

Note that Boreas Pass is not plowed throughout the winter, making a snow season ascent of this peak a major undertaking. Additionally, certain stretches of the Boreas Pass Road are known for winter avalanche activity. This peak is most easily attempted after the snows have melted in the spring or before the snow flies in the fall.
