From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

From Introduction: "The Butte Quadrangle, Montana (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Each environment was categorized as favorable, unfavorable, or evaluated according to criteria established in Mickle and Mathews (eds., 1978)."

From Introduction: "The Elk City Quadrangle (1º by 2º), Idaho and Montana, was evaluated to identify and delineate geologic environments that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Sheridan NTMS 1º by 2º Quadrangle (Fig. 1) in north-central Wyoming was evaluated to identify geologic environments that have characteristics favorable for uranium deposition. Only environments to a depth of 1500 m have been evaluated for this project."

From introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the cumulative thickness of sandstone in the Swift Formation.

Introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the total thickness of the Fox Hills-lower Hell Creek aquifer. Other maps show the altitude of the top (Feltism 1982a), cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) in the Fox Hills-lower Hell Creek aquifer. These maps are part of a series that describes the geology and potentiometric surface of selected rock units of Jurassic or younger age in the plains area of Montana.

From introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the norther Great Plains. The purpose of this map, which is a product of that study, is to show the altitude of the top of the Swift Formation.

Abstract: This report lists the machine-readable data files developed for the Madison Limestone and Northern Great Plains Regional Aquifer System Analysis (RASA) projects that are stored on magnetic tape and available from the U.S. Geological Survey. Record format, file content, and size are given for: (1) Drill-stem-test data for Paleozoic and Mesozoic formations; (2) geologic data from the Madison Limestone project; (3) data sets used in the regional simulation model; (4) hydraulic-head data for the Lower and Upper Cretaceous aquifers; and (5) geologic data for Mesozoic formations of the Northern Great Plains.

Introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the altitude of the top of the Lakota Formation and equivalent rocks. Other maps show the total thickness (Feltis, 1982a), cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) in the Lakota Formation and equivalent rocks. These maps are part of a series that describes the geology and potentiometric surface of selected rock units of Jurassic or younger age in the plains area of Montana.
