About this map

Paymaster Landing and Walters Camp anchor this 2012 survey of the lower Colorado River basin, where the waterway meanders through the Cibola Valley on the California-Arizona border. The landscape is defined by the shifting dynamics of the river, with numerous side channels and oxbow features like Three Finger Lake, Cibola Lake, and Walker Lake punctuating the riparian corridor. The presence of several small outposts such as Cibola Camp, Gilmores Camp, and Draper Ranch suggests a region primarily focused on remote river access and seasonal recreation rather than dense settlement.

Local industry and navigation are marked by distinct landmarks, including the remains of the Clip Mill and the prominent Lighthouse Rock near the southern bend of the river. A network of primitive roads, including Walters Camp Rd and Old River Rd, provides access across the arid washes like Turnaround Wash and Lopez Wash. This map is particularly useful for tracking the modern distribution of river camps and the complex hydrology of the backwater lakes along this stretch of the border.
