Rollins Pass, elevation 11,676 ft (3,559 m), is a mountain pass and active archaeological site in the Southern Rocky Mountains of north-central Colorado in the United States. The pass is located on and traverses the Continental Divide of the Americas at the crest of the Front Range southwest of Boulder and is located approximately five miles east and opposite the resort in Winter Park—in the general area between Winter Park and Rollinsville. Rollins Pass is at the boundaries of Boulder, Gilpin, and Grand counties. Over the past 10,000 years, the pass provided a route over the Continental Divide between the Atlantic Ocean watershed of South Boulder Creek with the Pacific Ocean watershed of the Fraser River, a tributary of the Colorado River.
The sign at the summit of Rollins Pass displays four proposed rail tunnel routes through the Continental Divide as alternatives to summiting Rollins Pass; it was the longer Moffat Tunnel that achieved this feat of engineering and was first utilized in February 1928.
A low rock wall and attached hunting blind (pit) at the Olson Game Drive on Rollins Pass. These features were hand-made by Native Americans; radiocarbon and lichenometric dating suggest occupation by Native Americans spanning the last 3,200 years, with diagnostic tools suggesting even older use of the site to more than 10,000 years ago.
