Berthoud Pass serves as the central crossing point for this high-altitude landscape where the Continental Divide separates the Grand and Clear Creek county lines. The area is defined by a dense network of mountain transit and recreation, featuring the sprawling Mary Jane Ski Area to the north and the Berthoud Pass Ski Area near the summit. The engineering of the Rockies is evident in the water diversion and mining infrastructure, including the Vasquez Tunnel and the August P Gumlick Tunnel.
