Discusses hydrogeology from the geological perspective. After describing the major features of 28 hydrogeologic regions of North America, the volume devotes eight chapters to discussion of the comparative hydrogeology of kinds of different bedrock regimes and surficial deposits; seven chapters to geologic processes including karstification, diagenesis, tectonics, ore deposits, and hydrocarbon migration intimately involved with ground water; and two concluding chapters to look at future scientific and societal problems related to ground water.
Region 1, Western mountain ranges
Published:January 01, 1988
The Western Mountain Ranges region (Fig. 3, Table 2, Heath, this volume) owing to its areal extent (more than 1.5 million km2) and large range in altitude (5,000 m) and latitude (35° to 62° N), includes perhaps the greatest diversity of geologic conditions and processes of all the regions of North America. Consequently, ground-water conditions also are highly varied.
The region includes 15 subregions. Of the subregions, 12 are mountainous subregions and 3 are intermontane and lowland subregions. Included with the mountainous subregions are intermountain basins in Montana and Colorado and individual coastal lowlands along the entire...
