Clear Creek is a tributary of the South Platte River, approximately 66 miles (106 km) long,[3] in north central Colorado in the United States. The creek flows through Clear Creek Canyon in the Rocky Mountains directly west of Denver, descending through a long gorge to emerge at the town of Golden, finally ending in the Colorado Eastern Plains where it joins the South Platte. Clear Creek is unusual in that it is a stream named "creek" fed by a stream named "river"; typically "rivers" are fed by "creeks"
