Summary

The San Juan basin is a significant physical and structural element in the southeastern part of the Colorado Plateau physiographic province. The San Juan basin is in New Mexico, Colorado, Arizona, and Utah and has an area of about 21,600 square miles. The basin is about 140 miles wide and about 200 miles long. In the 1980’s and 1990’s, the San Juan basin was the focus of the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) study. Investigation of the San Juan structural basin began in October 1984 with an objective, among others, to define and evaluate the aquifer system. As part of this analysis, a multi-publication series of reports were produced as Hydrologic Atlas 720 (HA-720) that described on 1:1,000,000-scale [...]

Purpose

This digital dataset was created as part of a U.S. Geological Survey study to be used as digital geologic input data for subsurface mapping and three-dimensional geologic framework modeling of the Intermountain West. The elevation, thickness, and extent of subsurface geologic units are required to define the geologic layering in any digital geologic framework model; these data, derived from previous USGS studies in the region, provide a fundamental starting point. The intended uses of this dataset include, but are not limited to, natural resource modeling, mapping, and visualization applications.
