2021 Map of Red Bluff Mountain NW

About this map

Castle Dome Plain defines the central sweep of this modern topographic study in Yuma County, Arizona. Produced by the U.S. Geological Survey in 2021, the map details a land of sharp relief and expansive basins typical of the Sonoran landscape. To the northeast, a notable Natural Arch is documented among the high contours, serving as a distinct landmark for those navigating the arid terrain. The map serves as a contemporary record of land management and surveying, illustrating the township and range divisions across the T5S R19W and T6S R18W boundaries. This recent data from the National Hydrography Dataset and National Elevation Dataset provides a precise view of the dry washes and elevation changes that characterize the region.
