About this map

Tioga and the surrounding high-plains landscape of Huerfano County are defined by a complex network of seasonal watercourses and historic irrigation systems. The Huerfano River traverses the northern section of the map, supported by engineered water management features like the Pino Ditch and Martin Ditch Number 2. Small, distributed settlements including Strong, Alamo, and Delcarbon are connected by a rural road network such as Twin Lakes Rd and various county routes, reflecting the region's ranching and agricultural foundations.

Local topography is marked by the eponymous Black Hills in the southwest and Bells Gap to the east. The land is heavily dissected by numerous arroyos, such as Ojo de Alamo Arroyo and Gordon Arroyo, which dictate the placement of local infrastructure and property boundaries. This 2019 survey provides a clear view of the modern land divisions and the persistent presence of historical nameplates across this stretch of Southern Colorado.
