1986 Map of Casa Grande

About this map

The Beaubien and Miranda Grant (Maxwell) dominates this landscape in northern Colfax County, where the high mesas of the Sangre de Cristo foothills meet industrial resource extraction. The settlement at Casa Grande and nearby Bartlett sit along the Vermejo River, anchored by agricultural and mining activity. The map reveals an intensive history of land use, from the Old Railroad Grade tracing the Canadian River to the extensive Strip Mine and numerous mines and Air Shafts concentrated in York Canyon. This area represents a complex geography of Spanish land grants and modern energy production, where deep canyons like Penitente Canyon and Stubblefield Canyon cut through high plateaus marked by Butler Flats and numerous Prospects. The transition from Colorado into New Mexico is clearly defined along the northern boundary, marking the divide between Las Animas and Colfax Counties.
