2021 Map of Monument Bluff

USGS Topo · Published 2021

About this map

The United States of America Estados Unidos Mexicanos international boundary cuts diagonally across this arid landscape, defining the southernmost reaches of Yuma County. This remote desert terrain is dominated by the volcanic remnants of the Pinacate Lava Flow, which spills into the Pinacate Valley near the eastern edge of the quadrangle. The namesake Monument Bluff serves as a prominent landmark overlooking the expansive Tule Desert, an area characterized by shifting sands and sparse vegetation. Surveyed recently, the map illustrates how the natural features of the Sonoran Desert intersect with the formal political line of the border, where the lack of modern infrastructure highlights the extreme environment and historical isolation of this borderland region.
