About this map

The San Juan River snakes through this high desert landscape, defining the northern boundary of the Navajo Indian Reservation. This late 1980s provisional study records a region shaped by deep watercourses and dramatic geological formations, including the prominent Lime Ridge and the sweeping Nokaito Bench. The map details the confluence of significant tributaries like Chinle Creek and Butler Wash, which have carved intricate drainage patterns into the surrounding plateaus.

Evidence of historical passage and topographical landmarks are noted throughout the terrain, from the namesake San Juan Hill to the curiously named Mule Ear formation. Along the river, Four Foot Rapids indicates the persistent force of the water in this arid environment. The inclusion of a singular Drill Hole suggests localized exploration efforts within this federally managed expanse, where traditional land divisions meet the winding natural borders of the Canyon.
