1989 Map of Additional Hill

About this map

The Navajo Indian Reservation boundary meets the eastern edge of the Kaibab National Forest in this high-desert landscape of Coconino County. The terrain is defined by the prominent Additional Hill and the winding course of Lockwood Canyon, while the local economy is evidenced by a network of essential water catchment features such as Lee Dam and Michelbach Tank. The map reveals a land managed for both conservation and indigenous heritage, where livestock and wildlife management are indicated by numerous named tanks including Malpais Tank and Needmore Tank. This late 20th-century survey provides a clear view of the complex water infrastructure, showing several Pipeline segments and Trans Lines that crisscross the arid stretches near Lava Wash and Cedar Wash. The distinct Rim feature underscores the dramatic elevation changes that characterize this portion of Northern Arizona.
