Mosquito Pass was built to connect the towns of Alma to the east, with Leadville to the west. It is the highest crossable vehicle mountain pass in the U.S. outside of Alaska. While there are higher vehicle passes, they are all out and back. The trail crosses the Continental Divide, between the Arkansas and South Platte Rivers.
The Mosquito Range is also home to five 14,000′ peaks; Mt Sherman, Mt Democrat, Mt Cameron, Mt Lincoln, and Mt Bross.
