The town of Hanna sits at the northern edge of this high-plains landscape, where the residential street grid gives way to a sprawling network of water management and varied terrain. In this 2015 U.S. Geological Survey study, the importance of water in this semi-arid region is evident through features like Big Ditch, Stevies Lake, and the Martinez Reservoir in the southwest. The geography is defined by a series of prominent rises and depressions, including Halleck Ridge, Wilson Ridge, and the Sand Hills, which create natural corridors like Wilson Gap and Quealy Gap.
