2011 Map of Butler Mountains

About this map

Butler Mountains rise in the northwestern corner of this arid landscape, located along the international border between Arizona and Sonora. The topography is defined by a sparse desert floor marked by a complex network of ephemeral drainage patterns that flow southeastward across the border region. This 2011 survey captures the remote character of the Butler Mountains and the surrounding basin before significant modern alteration, showing only the natural relief and the primary boundary line between the United States and Mexico. The lack of named settlements or man-made structures highlights the isolation of this corner of the desert, where the geological formations of the mountains provide the only prominent landmark.
