Big Norris Spring and Little Norris Spring provide a rare glimpse into the hydrological network of this arid reach of Val Verde County. The terrain is deeply carved by a series of intermittent watercourses, including White Draw and Threemile Draw, which characterize the drainage patterns of the western Edwards Plateau. Transportation through this remote landscape is limited to Dolan Creek Rd, which follows the contours of the valley floors. The map meticulously traces the paths of Dolan Cr and its tributaries, such as Middle Dolan Cr and W Dolan Cr, illustrating how these drainages dictate the local topography. This 2019 survey captures the area in its contemporary state, showing the complex interplay between the occasional springs and the extensive draw systems that define the geography of the region.
