The rarest of Army Chief Engineer E. F. Ruffner’s survey maps of southern Colorado and northern New Mexico, the present map focuses on a military road that crosses the Continental Divide at present-day Wolf Creek Pass near Pagosa Springs. The road runs from Alamosa, Colorado, south toward Abiquiu and El Rito, New Mexico. The area shown is bounded on the north and east by the Rio Grande del Norte and was compiled from “traces made from maps of the Geological Surveys West of the 100^th Meridian,” as is noted in the lower margin. Several other roads cross the region, including the Chama, Park View, and Conejos Toll Roads. Waterways are named, but topography is not shown. Random distances and elevations are given.
