1966 Map of The Hogback North

USGS Topo · Published 1986

About this map

The Hogback dominates this San Juan County landscape, forming a dramatic geological spine that separates the western reaches of the Navajo Indian Reservation from the valley to the east. By the mid-1960s, this area supported significant energy and agricultural infrastructure. The presence of the Hogback Oil Field and various pipelines reveals the industrial footprint of petroleum extraction, while the Fruitland Irrigation Canal draws water from the San Juan River to sustain the Jewett Valley area. The confluence of the Chaco River and the San Juan River highlights a complex drainage system, further marked by the presence of Tailings Ponds and several Gravel Pits, indicating an era of active mineral processing and land use within the reservation boundaries.
