About this map

Johnson Cem and a remote Landing Strip highlight this 1970s topographical record of the canyonlands in Las Animas County. The landscape is deeply carved by the Purgatoire River and Chacuaco Creek, which define the complex network of side canyons like Bruno Canyon and Johnson Canyon. This map documents a ranching infrastructure reliant on scattered water sources, including the Garfield Windmill, Round Corral Windmill, and several named springs such as Sandoval Spring and Barriet Spring.

Transport is limited to a sparse network of Jeep trails, reflecting the isolated nature of the terrain. The inclusion of the Double Tank Windmill and numerous water pockets like Bar Four Pocket underscores the critical importance of water management for livestock in this arid portion of southern Colorado. The map also traces the winding courses of Alejandro Canyon and Seven Pocket Canyon, providing a detailed view of the regional drainage patterns before the mid-1980s updates.
