The region traversed by the Colorado and its tributaries is for many reasons of intense interest to the people of the United States. Here was the home of that forgotten people of which there is almost no record except the hieroglyphics on the rocks, the ruins of their irrigation systems, and the cliff dwellings by which they are most widely known; here were Spanish missions whose history extends b

In order to determine the location of undeveloped water powers the United States Geological Survey has from time to time, alone and in cooperation with State organizations, made surveys and profiles of some of the rivers of the United States that are adapted to the development of power by low or medium heads of 20 to 100 feet.The surveys are made by means of plane table and stadia. Elevations are

To my mind the period of direct contact with nature is the true "heroic age" of human history, an age in which heroic accomplishment and heroic endurance are parts of the daily routine. The activities of people on this stage of progress deserve a place among the cherished traditions of the human race. I believe also that the sanest missionary effort includes an endeavor to assist the uncivilized m

Investigation of water resources by the United States Geological Survey has consisted in large part of measurements of the volume of flow of streams and studies of the conditions affecting that flow, but it has comprised also investigation of such closely allied subjects as irrigation, water storage, water powers, underground waters, and quality of waters. Most of the results of these investigatio

Utah, like other states in the arid region of the United States, points with just pride to her present and future agricultural developments. She proudly boasts, and no doubt justly too, that her fields of green vegetation are inexhaustible and always expanding, and with due vigilance and care on the part of her land holders these fields will bring forth the proper supplies for man for an indefinit

Scope.-The finer debris transported by a stream is borne in suspension. The coarser is swept along the channel bed. The suspended load is readily sampled and estimated, and much is known as to its quantity. The bed load is inaccessible and we are without definite information as to its amount. The primary purpose of the investigation was to learn the laws which control the movement of bed load, and

This paper contains 203 water analyses, which were made in the chemical laboratory of the United States Geological Survey. Most of these analyses have been published elsewhere, but many of the original documents are out of print, and are therefore obtainable with difficulty. Furthermore, the form of statement given the analyses has varied from time to time, so that the printed records show a lack
