Arapaho Pass (11,950′), Front Range
From the east, access to Arapaho Pass can be found along a rough 2WD road that provides access to the Fouth of July Trailhead. The trail begins in dense forest with wonderful fields of wildflowers blooming in the summer months. For part of the hike to the top of the pass, the trail follows an old stage-coach road. It also passes the remains of the Fourth of July Mine near treeline. Miners dug silver ore from the Fourth of July Mine in the late 1800s. In the early 1900s they switched over to searching for copper. Over the 300-foot mine shaft once stood a timber head frame, where miners and equipment were lowered into the main tunnel, which was over a mile long. At the top, Arapaho Pass sits on the famous Continental Divide that runs through the Colorado mountains.
