in North America (5th highest in the world) and is only open in the summer. Colorado 103 continues east from Echo Lake to Squaw Pass, from which it connects, via Clear Creek County Road 103 and Jefferson County Road 66, to Bergen Park from which Colorado 74 leads to Evergreen Colorado. The Guanella Pass Scenic Byway passes within west of Mount Evans, linking Georgetown and I-70 with Grant and US 285, to the south. A marked hiking trail roughly parallels the highway from Echo Lake to the summit, and a second marked trail links Guanella Pass to Mount Bierstadt. A difficult side route of the latter climbs to the northeastern peak of The Sawtooth, from which an easy ridge leads to the summit of Mount Evans. Most of the Mount Evans massif is now part of the Mount Evans Wilderness area in Arapaho National Forest and Pike National Forest. The exception is a narrow corridor along the highway from Echo Lake that is excluded from the wilderness. Summit Lake Park and Echo Lake Park, are part of the historic Denver Mountain Parks system. History Mount Evans was originally known as Mount Rosa or Mount Rosalie. Albert Bierstadt named it for the wife of Fitz Hugh Ludlow, whom he later married. The name is also a reference to Monte Rosa, the highest peak in Switzerland. Bierstadt and his guide, William Newton Byers, approached the mountain along Chicago Creek from Idaho Springs in 1863, and spent several days painting sketches of the mountain from the Chicago Lakes before climbing to Summit Lake and onward to the summit. Bierstadt's sketch, Mountain Lake, accurately portrays the view of Mount Spalding over the Chicago Lakes. His painting, A Storm in the Rocky Mountains, Mt. Rosalie, is based on that and other sketches. A second claim to be the first to ascend is attributed to Judge Lunt and a friend in 1872. William Henry Jackson, attached to the Hayden Survey, visited the Chicago Lakes in 1873, where he took numerous photographs; the summit of Mount Evans is barely visible in several of these, peeking over the col between upper Chicago Lake and Summit Lake. The Hayden survey reported that Mount Rosalie was 14,330 feet above sea level, measured by triangulation. In 1895, 30 years after he was forced to resign as governor because of his part in the infamous Sand Creek Massacre and its subsequent cover-up,
