Page 1286 - The cutting of the lower intake, after mature deliberation, and upon the insistence of several of the leading men of the Valley, was decided upon. We hesitated about making this cut, not so much because we believed we were incurring danger of the river's breaking through, as from the fact that we had been unable to obtain the consent of the Government of Mexico to make it, and we believed that we were jeopardizing our Mexican rights should the cut be made without the consent of the Government. On...
Page 1156 - Colorado where extreme characteristic desert conditions prevail, such as arid treeless plains, old lake beds and sand hills — such conditions as are found in the Sahara of Africa and in the delta regions of the Nile. The appellation may properly be confined to the regions reached by the deposition of the silt of the Colorado whether in the form of deltas or at the bottom of ancient lakes. I should also include the bordering detrial slopes from the contiguous mountains.
Page 1163 - California, but the most pronouncd feature of this character is to be found well out in the delta near Volcano Lake. Here on a saline plain a few miles in extent innumerable small mud cones, solfataras, and boiling pools of mud and water emit steam, smoke, and sulphurous gases, accompanied by a dull rumbling sound. According to the traditions of the...
Page 1156 - ... Desert." This was not the intention or wish of the author of the name. It was intended to apply it strictly to the typical desert area of the lacustrine clays and alluvial deposits of the Colorado where extreme characteristic desert conditions prevail, such as arid, treeless plains, old lake-beds, and sand hills — such conditions as are found in the Sahara of Africa and in the delta regions of the Nile. The appellation may properly be confined to the regions reached by the deposition of the...
Page 1460 - It is the cost, not the physical difficulties, which stands in the way. It may be stated that as a general rule a sufficient amount of storage can be artificially created in the valley of any stream to rob its floods of their destructive character; but it is equally true that the benefits to be gained will not ordinarily justify the cost.
Page 1271 - One hundred and twenty-five thousand acres of land [the report said] have already been taken up by prospective settlers, many of whom talk of planting crops which it will be absolutely impossible to grow. They must early find that it will be useless to attempt their growth.
Page 1142 - ... removed by erosion. Many mountain ranges are undoubtedly buried beneath the detrital material. The present Gulf of California once extended much farther north than at present and filled what is now the Imperial Valley of California. The silt of the river was distributed far and wide in this sea which was partially cut off from the broad Pacific by a chain of islands. During and after the Glacial Period, when precipitation is believed to have reached its peak, the river had its greatest volume...
Page 1140 - ... feet above the sea. Here, at last, was discovered the greatest break through the western Cordillera, leading from the slopes of Los Angeles and the Pacific into the interior wilderness. It had no place upon the maps, and had not been traversed by surveying parties or wagons. From the summit we could look eastward and southward into a deep and apparently interminable valley stretching off in the direction of the Gulf of California. This pass was evidently the true gateway from the interior to...
Page 1437 - ... RIVER. There is transmitted herewith a letter from the Secretary of the Interior setting out the work done under joint resolution approved June 25, 1910, authorizing the expenditure of $1,000,000, or so much thereof as might be necessary, to be expended by the President for the purpose of protecting lands and property in the Imperial Valley and elsewhere along the Colorado River in Arizona.
