About this map

Velasquez Plaza and Sarcillo sit along the northern edge of this map, tucked into the Picketwire Valley where the Purgatoire River and its southern fork carve through the high terrain. This area of Las Animas County is defined by an intricate network of drainage systems, including the namesake Little Pine Canyon and the expansive Alamosa Canyon. The landscape reveals a complex topography of deep cuts such as Chimney Canyon, Lorencito Canyon, and Oso Canyon, which feed into the primary river valley.

The settlement pattern is concentrated near the water sources in the north, while the southern reaches of the map ascend toward the Park Plateau. This layout reflects the traditional reliance on the river valleys for habitation and agriculture in an otherwise arid, canyon-riven environment. Numerous named branches like the Right Hand Fork Martinez Canyon and Left Hand Fork Oso Canyon illustrate the detailed watershed mapping necessary for land management in this part of Colorado.
