Silver Found on McClellan Mountain

In the mid-1860s, Colorado's Argentine Pass was a pretty busy place. In 1864, Colorado's former provisional territorial governor Robert Steele discovered silver on McClellan Mountain, and miners would need a road to get them there. What they got was a ten-mile road that followed a portion of the Guanella Pass, then diverted to climb up the side of Argentine Peak.

Colorado's Highest Mountain Pass

Colorado's highest mountain pass, Argentine Peak, was never a paved road. Reaching over 13,200 feet at the summit, what was known as the Argentine Pass Toll Road remains a dirt road covered in rocks, boulders, and usually lots of snow.
