About this map

The high desert landscape of Petrified Forest National Park and the surrounding plateau dominate this 1981 survey of northeastern Arizona. Centered on the community of St Johns, the topography reveals a complex network of seasonal drainages and permanent water features, including the Colorado River and the Zuni River. The presence of Lyman Lake and Zion Reservoir indicates the critical role of water management in this arid region.

Evidence of early 1980s infrastructure is clearly visible, from the Atchison Topeka and Santa Fe railroad tracks passing through Adamana to the runways of the St Johns Airport. The map highlights the intersection of public lands and private enterprise, showing the vast Petrified Forest National Wilderness alongside established transportation corridors like Route 180 and Route 666. Geological features such as Potter Mesa and Puerco Ridge provide a detailed look at the local terrain during this era of southwestern growth.
