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.
