1966 Map of Old Pine Spring

About this map

The Navajo Indian Reservation landscape is defined here by a complex system of drainage washes and vital water sources within the high-elevation terrain of San Juan County. Recorded in the mid-1960s, the map highlights the critical importance of localized water points such as Old Pine Spring and Old Sawmill Spring, which served as essential landmarks for movement and resource management across this arid plateau. The topography is deeply carved by water-eroded features including To-nil-choni Canyon and the expansive Hidden Valley. A network of seasonal waterways like Tocito Wash, Porcupine Wash, and Tse-nas-chii Wash underscores the natural drainage patterns that have shaped the land's utility and character for generations. These features provide a clear view of the natural infrastructure supporting local life before more modern developments altered the region.
