2021 Map of Augustine Pass

USGS Topo · Published 2021

About this map

Augustine Pass serves as the focal point for this survey of the arid divide between the Chuckwalla Mountains to the north and the Chocolate Mountains to the south. The landscape is defined by its transit history, prominently featuring The Bradshaw Trl, a historic overland stage route that once connected the gold fields of the Colorado River to the coast. This corridor remains marked by modern desert tracks including Augustine Rd and Dupont Rd, which navigate the complex topography of dry washes like Arroyo Seco. The map also captures the administrative boundary where Riverside Co meets Imperial Co, cutting through the high desert terrain near Surveyors Pass and Niland Rannels Rd.
