Clear Creek, a vibrant waterway roughly 66 miles long, originates in the Rocky Mountains west of Denver, finally meeting with the South Platte River. The contrast in the water's color and flow is often noticeable, with Clear Creek's clear, fast-moving water meeting the South Platte's slower, sometimes more opaque flow.
