2011 Map of Bryan Mountains

About this map

Bryan Mountains dominate this arid landscape in Yuma County, appearing here in a digital 2011 topographic rendering. The terrain is characterized by a complex network of ephemeral desert washes and intermittent drainage patterns that carve through the desert floor. This Usgs sheet represents the modern era of high-resolution mapping, utilizing data from the National Hydrography Dataset and imagery from the Naip. The absence of named settlements or infrastructure reflects the preservation of this remote desert environment, where the topographic contours provided by the National Elevation Dataset reveal the sharp physical relief of the peaks. Researchers of the Arizona borderlands will find this record essential for understanding the physical geography and hydrography of the region at the start of the second decade of the 21st century.
