The composition of the river and lake waters of the United States
In the summer of 1903 the late Richard B. Dole, chemist of the water-resources branch of the United States Geological Survey, began a systematic investigation of the composition of the river and lake waters of the United States. His plan, which developed gradually, was to have analyses made of the different waters in such a manner as to give the average composition of each one for an entire year.

The data of geochemistry
Upon the subject of geochemistry a vast literature exists, but it is widely scattered and portions of it are difficult of access. The general treatises, like the classical works of Bischof and of Koth, are not recent, and great masses of modern data are as yet uncorrelated. The American material alone is singularly rich, but most of it has been accumulated since Roth's treatise was published. The

The San Juan Canyon, southeastern Utah: A geographic and hydrographic reconnaissance

The exploration of the canyon, which was financed jointly by the United States Geological Survey and the Southern California Edison Co., had as i

It is about 27,000 square miles in area and includes the northern part of Utah, a small part of eastern Nevada, the southeast corner of Idaho, and the southwest corner of Wyoming.The eastern part of the area consists of mountainous highlands; the western part chiefly of low-lying plains. The lo

A section of the Paleozoic formations of the Grand Canyon at the Bass trail
The thick series of horizontal strata of Paleozoic age which makes the greater part of the wall of the Grand Canyon is probably broadly familiar to more people than the strata exposed in any other area in the western United States. Each detail of form or color in the wall is so definitely associated with a bed or set of beds in the series that these strata are the very elements of the canyon lands
