Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.

Previous studies have shown the Escalante Valley, Utah, is subsiding due to groundwater withdrawal. The magnitude and spatial pattern of this cm/yr.-scale subsidence is mapped with satellite data from a synthetic aperture radar (SAR) using interferometric SAR (InSAR) processing techniques.

"The two reports published here contain elements which contribute substantially to this broader spectrum of Southwestern cultural change. While primarily descriptive in nature, these two site reports, one from the western Kayenta area and one from the margin of the Mesa Verde area and the eastern Kayenta, suggest that the changes which occurred in the more centralized portions of these regions were directly related to what happened on the margins. That, while the site densities and population aggregates may not have been as high, the same factors affected these marginal areas. That conclusion could be expected, but what may not be expected is the differential response which appears to have occurred. After reading these two reports, it appears that it may be possible to discern elements of change in these fringe areas that, once defined, will provide new insight into what happened and why and in what are presently the better known areas of the Southwest. These two papers are important, in sum, not only because they are reports of work in poorly known areas, but because they do provide analyses of fringe areas, they help us to understand the Southwest generally"--From preliminary introduction.

This report characterizes the relationship of geology to groundwater occurrence and flow, with emphasis on determining the thickness of the valley-fill aquifer and water yielding properties of the fractured rock aquifers. Develops a water budget for the drainage basin and classifies the groundwater quality and identifies the likely sources of nitrate in groundwater.
