1986 Map of Peach Springs

About this map

The Colorado River carves a deep path through the center of this mid-1980s survey, defining the northern boundary of the Hualapai Indian Reservation. This landscape is dominated by massive geological formations including the Shivwits Plateau and Sanup Plateau to the north, and the Music Mountains to the south. Along the river, a sequence of treacherous water features are meticulously identified, such as Triumphal Arch Rapids and Two Hundred and Thirty-nine Mile Rapids, providing a precise record of the river's character before modern changes.
