- The Ancient Volcanic Rocks of South Mountain, Pennsylvania
- From introduction: In December, 1892, as the result of field work on the part of Dr. G. H. Williams in the northern and of the writer in the southern portion of South Mountain, there appeared a preliminary description of two of the rock types, in which their identification as ancient volcanics was announced. In this bulletin it is proposed to substantiate that identification with more detailed proof. It is further proposed to show that these ancient igneous rocks were, at the time of their consolidation, identical in character with their recent volcanic analogues, and that their present differences are due to subsequent changes, chief among which has been devitrification. It is also proposed to recognize these facts in the nomenclature.

- The Colorado Formation and its Invertebrate Fauna
- From preface: The following review of one of the Upper Cretaceous faunas as developed in the interior region of the United States has grown out of the study of a collection of fossils found by me in Huerfano park and adjacent localities in southern Colorado. This collection, the greater part of which was obtained during the summer of 1890, proved to be especially interesting because it afforded data for the closer correlation of certain Cretaceous strata in Utah with those east of the mountains, besides adding a considerable number of new species to the fauna of the Colorado formation. Dr. C. A. White, under whose direction the field work was done, generously assigned these fossils to me for study with a view to publishing the results, and I am greatly indebted to his sympathetic aid in every phase of the work.

- A Dictionary of Geographic Positions in the United States
- From introduction: For several years the Division of Topography of the United States Geological Survey has been engaged in compiling positions determined within the United States which are believed to be of sufficient accuracy for use in the preparation of its maps. This compilation has been found extremely useful in the office, and it is believed that its usefulness will be greatly extended by placing it before the public. This list comprises between 9,000 and 10,000 positions. To publish it in extenso, with descriptions of the stations, their latitudes and longitudes, the distances and azimuths to neighboring stations, and the methods of determination, would extend this bulletin beyond all reasonable limits. To avoid making too bulky a volume, it has been decided to publish merely the latitudes and longitudes, with abbreviations indicating the authority, and references to the publications in which other data relating to the positions may be found.

- The Geology of Nantucket
- Letter of transmittal: I have the honor to transmit herewith a report on the geology of the island of Nantucket. This report embodies a portion of the work which I have done in connection with the general study of the Atlantic coast line. Although part of a much more extended inquiry, it seems well to publish the results contained in this memoir in advance of my general report for the reason that the region constitutes a distinctly bounded field and also because the problems considered in this report have an important bearing on work which is in the bands of other divisions of the Survey.
- Geology of the Big Stone Gap Coal Field of Virginia and Kentucky
- From introduction: In presenting this paper the writer has two objects in view. The first is to add to the general knowledge respecting the geology of this central district [Appalachian coal basin]. The groups determined in this region will be carried over the adjoining territory if they can be distinguished and they afford a type-section of the Coal-measures where they are probably best developed. The results are not put forth as final, but as representing the most probable conclusions from the observed facts.
- Geology of the Castle Mountain Mining District, Montana
- From preface: This memoir is a general study of the region described, and not a detailed report. The field work upon which it is based formed a part of the work of mapping the areal geology of the Little Belt Mountains sheet of the Geological Survey. The topographic map, made in 1882 by the Northern Transcontinental Survey, is too small in scale and too general in character to warrant more detailed work; but as the facts obtained are of interest, and the region is one of economic importance, it has been considered worthy of a special treatment.

The evidence thus far gathered shows that a large body of ice, originating in the ice sheets of the Yellowstone National Park, pushed northward, filling the upper valleys of the Yellowstone and extending down that stream 36 miles north of the park boundary.

- The Moraines of the Missouri Coteau, and their Attendant Deposits
- Introduction: It seems important that several general facts should be stated for the full understanding of terms used and allusions made in this report. The field considered is the region lying between the Missouri and James rivers, and between the latitudes of Jamestown, N. Dak., and Huron, S. Dak. 1. As has been stated in papers published by Chamberlin, Upham, myself, and others, several more or less distinct moraines have been observed in the Mississippi Valley. It has been found convenient to distinguish the outermost three by special names. President Chamberlin has named them, beginning with the outermost, Altamont, Gary, and Antelope moraines, from localities south of Big Stone Lake, and these names have been quite generally adopted. Upham and others have named them the First, Second, and Third, and as the outermost two are the more prominent, they have also been called the Outer and Inner moraines. Each of these, especially the First and Second, has subordinate divisions, which mark the borders of the different lobes into which the margin of the ice sheet was often divided. 2.) It is assumed that the reader is familiar with the generally recognized features of drift formations, such as the undulating topography and the series of drift deposits, covering an area with successive layers of till in a manner which might be compared to a nest of spoons of assorted sizes, the smaller lying inside the larger. Of these spoonshaped deposits, the moraines form the outer rims. 3.) As the moraines are the most conspicuous features of the drift formations, we may take them as the basis for dividing the subject. Not only are they the most conspicuous features of the topography, but they mark culminations of glacial activity. We therefore propose reviewing our subject under the following heads: I.) The First …
