Results of 1900 expedition on Queen Charlotte Islands describing natural history.

From introduction: The two papers published here refer practically to the whole region included in the National Park. The one. Part I, treats primarily of the geology, the development of the great volcano, Mount Mazama, and its collapse, which gave birth to Crater Lake; the other, Part II, deals with the petrography, and gives a special description of the various rocks occurring in the park.

From introduction: Since 1898 the United States Geological Survey has been carrying on a systematic investigation of the mineral resources of Alaska.As the northern mining districts of southeastern Alaska had already been the subject of an investigation by Dr. Becker in 1895,a and as the Ketchikan district was being rapidly developed, it was decided to spend the greater part of the short season in the Ketchikan district and in the fall to make a more hasty reconnaissance of the northern belt, in order to obtain a general familiarity with the region and, if possible, to establish some correlations. This plan was carried out, and the results of the work are embodied in the following report.

From introduction: In response to an urgent demand by the public, the Geological Survey, in 1900, undertook a topographic and geologic reconnaissance of the southern half of the Seward Peninsula.( The area mapped embraced the more important gold fields of the peninsula. The topographic map made in 1900 included the drainage of Bering Sea from Cape Darby to Port Clarence, the southern drainage of Grantley Harbor and Imuruk Basin, and the northern drainage of Norton Sound. A geologic reconnaissance was also made of the York mining district and of part of the Kuzitrin drainage.

Results of 1900 biological expedition to document the Hudson Bay. Examination of species of plants and animals.

An examination of coal deposits along the Yukon River conducted in 1902 mostly along the river banks from Dawson, Yukon to the delta.

From introduction: The aim of the present paper is to put on record such observations relating to the general geology of the region traversed as it is thought may be of interest, more particularly to the people of Idaho and Oregon, and also in certain instances serve to supplement the report referred to on artesian conditions.

From introduction: This report presents the findings of surveys of the extent of the oil fields in the gulf coastal plain.

From introduction: This report contains the results of the primary triangulation and primary traverse executed by the USGS during the fiscal year 1902-3.

From introduction: This report presents the results of reconnaissances on the coal formations of the area of Kansas south of the Kansas River.

From introduction: This report contains the results of primary triangulation and primary traverse in the eastern and western divisions of the United States.

From introduction: It is the purpose of this bulletin to combine the results obtained by the USGS parties that have visited the region, together with the information derived from a study of specimens of tin ores and associated minerals recently brought from the York region by outside parties.

This report consists of three parts: (1) An annotated list of the generic names of mammals; (2) an alphabetical list of the families of mammals, and (3) a classified list of the generic names, arranged by orders and families.

General account with outline of route and life zones, and lists of mammals and birds.

From letter of transmittal: The report contains 63 contributions from 37 members of the Survey who have been engaged more or less continuously throughout the year in economic work, together with brief statements by the geologists in charge of the section of metalliferous ores and the section of nonmetalliferous economic minerals, of the extent and character of the economic work being carried on in the Survey.

From letter of transmittal: This manuscript is based on geologic and topographic reconnaissance survey, made during the summer of 1903, of an important placer-gold district in the northeastern part of Seward Peninsula.

From letter of transmittal: This report contains the economic results of a reconnaissance of these gold fields of the Yukon basin which was carried out in 1903.

From introduction: This report is a summary of the present knowledge of limestone beds in southwestern Pennsylvania.

From letter of transmittal: It is believed that this report will stimulate the mining industry by making available, in compact form, the accumulated results of the experience of mining men in this field and by directing attention to those mining methods developed in older districts which appear to be adapted to the conditions prevailing in Alaska.

From introduction: This report is made in response to a general demand for information a reconnaissance of the petroleum and coal fields in the vicinity of Controller Bay and Bering River and of the petroleum fields on the west shore of Cook Inlet and at Cold Bay made during 1903 and 1904.
