From introduction: This survey was the first systematic work undertaken in this geologic province since the Geological Exploration of the Fortieth Parallel, in 1869, and was the first detailed geologic examination of a wide area in the Wasatch Range. Hence, an unusual amount of general geologic work in the region surrounding the special field was required to establish fundamental geologic facts.

Report describing the geology of Long Island based on surveys and research conducted 1903-1905, with a particular emphasis on glacial deposits and formations from the Pleistocene epoch. It includes a broad discussion, with tabular summaries.

This is a report on the middle triassic marine invertebrate faunas of North America.

This is a report on the copper deposits of Ray and Miami, Arizona.

Study of the geology and ore deposits of the Breckenridge District in Colorado.

From introduction: The growing economic importance of the Carrville district, Trinity County, California merits notice, and it is hoped that this brief report will direct attention toward it, to the end that mining in general may be benefited.

From preface: The present volume is the tenth of a series of annual bulletins treating of the progress of mining in Alaska and summarizing the results achieved during the year in the investigations of the mineral resources of the Territory.

From introduction: This is the most current attempt to locate all the mining districts of the western states.

From introduction: The object of this bulletin is twofold-to locate definitely and to describe accurately the marbles and dolomites of eastern Vermont, with a view to setting forth their possible economic uses and to discuss whatever features of scientific interest they may present.

From introduction: This report is a guide to the geology and scenery of Glacier National Park.

From preface: This report satisfies the demand of the public for reliable information and to gather data which should be of use in planning further geologic work in Nevada.

From introduction: The present report embodies the results of reconnaissance studies in the nineteen mining districts of Lemhi County, Idaho.

From introduction: This report determines the geographic distribution and thickness of the bituminous shale, or oil shale, or tar shale of the Green River formation of the Uinta Basin in Colorado and Utah.

From introduction: This report is based on a hasty reconnaissance made during the summer of 1910 and on several explorations made by the writer in the years 1900 to 1905.

Introduction: This report deals primarily with the volcanic phenomena of the region as determined in the field and laboratory.

A collection of writings on the shorter contributions to general geology.

Introduction: the following report is the first systematic account of fossil plants from the state of South Carolina.

Preface: The present paper is the first of a new series to be published by the Geological Survey under the title "Shorter contributions to general geology."

Abstract: The primary purpose of the investigation was to learn the laws which control the movement of bed load, and especially to determine how the quantity of load is related to the stream's slope and discharge and to the degree of communication of the débris.

Introduction: In the following pages a number of selected analyses or tests of the oil and gas from this field are given, with such descriptions of the analytical methods used as are necessary to an understanding of the results.

Introduction: The interpretation of the data furnished by the study of these fossils has been hindered somewhat because the exact stratigraphic location of much of the material is unknown. It was gathered with regard merely for the general stratigraphic and geographic position. However, as a knowledge of the general relationship forms to those of other areas is in itself of value to the stratigrapher and systematist it has seemed desirable to describe and figure the species.

introduction: The present paper, which in some respects is supplementary to another recent one on the same region, is based on a series of vertebrate remains collected during the field season of 1916 for the United States Geological Survey by J.B. Reeside, jr., and F.R. Clark.

From introduction: The purpose of the field work was to investigate the geology of the county, particularly the structure or lay of the oil-bearing strata and the results of drilling to date. Structural conditions in the producing fields were determined by running level lines to the wells and correlating the data recorded in the well logs generously furnished by the operators.

This report describes the results of expeditions to map the geologic and topographic features of the Kantishna region of Alaska.
