Fig. 3. A relatively stable topographically and ecologically complex area located north of the Canadian River and east of Conchas Lake Dam as viewed from the south side of the river, San Miguel County, New Mexico. North of Canadian River (CL4); V near middle shows the area with openstructured mesquite, grassesweeds, and junipers along an unpaved road on the upper bench near a precipice from which individuals of Aspidoscelis neomexicana, A. tesselata C, and A. exsanguis, but not A. sexlineata viridis or A. tesselata D, have been collected; lower V shows bench near the river with dense mesquite, grasses, and weeds in which only individuals of A. neomexicana have been observed.
