| Relative position | Rainbow Gulch is a north- and west-flowing tributary to the Middle Fork Koyukuk River and is located 2 to 3 miles northwest of Minnie Creek Lake. Reed (1938) described Rainbow Creek as running a little north of west, which would coincide with the lower part of the creek. The reference point for the prospects on this creek thus has been plotted near a cabin shown on the topographic map on the lower part of the creek (sec. 35, T. 31 N., R. 11 W., of the Fairbanks Meridian). The location is accurate within a 1-mile radius. |
