Water resources of the Edwards limestone in the San Antonio area, Texas
The water discharged from the large springs of San Antonio and most of the deep wells of the San Antonio area comes from a common reservoir in fissures and solution channels in the Edwards limestone.
The water enters the limestone in a zone of outcrop along the Balcones escarpment, which crosses the northern parts of Bexar and Medina Counties and extends a long distance both to the east and west o

Welded rhyolitic tuffs in southeastern Idaho
Rocks of rhyolitic type in eastern Idaho and adjacent parts of Wyoming were observed by the Teton Division of the Hayden Surveys under Orestes St. John (Report of the geological field work of the Teton Division, U.S. Geol. and Geog. Surv. Terr., 11th Ann. Rep., pp. 498–504, 1879), who described them as trachytes. He noted their relations to different types of underlying sedimentary rocks and their

Pre‐Cambrian and Paleozoic vulcanism of interior Alaska
The history of vulcanism in Alaska is a topic of great universal interest, but one which has had no adequate treatment. For some years the writer has been accumulating comparative data on this subject, and it is hoped that this information may some time be sufficiently amplified and coordinated to justify a general description of the sequential igneous history of Alaska. The scope of such an under

The igneous rocks of the Highwood Mountains of central Montana
The study of the Highwood Mountains was undertaken by a group of men from Harvard University under a grant from the Shaler Memorial Fund of the Department of Geology. The work was under the general direction of Larsen, who, with the assistance of Norman A. Haskell, mapped most of the volcanic rocks. Hurlbut and Griggs worked mostly on the laccoliths, Burgess on the stocks, and Buie on the dikes. T

The pre-Cambrian igneous rocks of eastern Pennsylvania and Maryland
The Blue Ridge and Piedmont geomorphic provinces, topographically distinct but geologically a unit, extend southwestward across eastern Pennsylvania and central Maryland, in a belt with an average width in these States of some 50 miles. In these provinces are exposed the crystalline formations of the Atlantic belt. Gneisses (with sporadic interbedded graphitic schist and marble), quartz-schist, cr

Shore benches on the island of Oahu, Hawaii
The Island of Oahu is third in size in the Hawaiian group and lies in the mid-Pacific about 2,100 miles southwest of San Francisco. Honolulu, the capital and principal port of this group, is on Oahu. Two dissected volcanic domes, the Waianae Range (4,035 feet high) and the Koolau Range (3,105 feet high) make up the island. They are surrounded by a nearly continuous coastal plain, in places reachin
