| Relative position | Colorado Creek is a northeast-flowing tributary of Coal Creek, which is a northeast-flowing tributary of the Yukon River. Colorado Creek joins Coal Creek just south of the major placer activity on Coal Creek (CY006). Colorado Creek is about 7 miles long; coordinates for the mines have been arbitrarily placed at the approximate midpoint of the creek, in the NE1/4 section 19, T. 5 N., R. 22 E., of the Fairbanks Meridian. The exact location along Colorado Creek where mining was conducted is uncertain, although the lower section of Colorado Creek seems most likely. The location is accurate to within 4 miles. |
