Show The Great Shoshone Dam Of several great storeage dams at present pre-sent under construction by the Reclamation Recla-mation service perhaps the most strikingly strik-ingly Interesting are the three masonry mason-ry dams knows as the Shoshone, the Palhllndcr, and the Hooscvelt. Tho highest of these, tho one in fact that will be distinguished as the highest dam In the world, is being built In the canyon or the Shoshone River In northwestern Wyoming, six miles west of the town of Cody, so named after Col. W. F. Cody, better known as "Buffalo Hill.,, Tho Shoshone, or the Stlnnlng Water River, as It was originally named, because be-cause of the occurrence along its course of springs giving out noxious gases, rises in northwestern Wyoming In the spurs of the eastern slope of the (Jrcat Continental Divide' known as the Absoraka and Shoshone ranges. The drainage basin of the river above tho Shoshone dam Is about 13,000 square miles in extent, varies In altitude from I 5,000 to 12,000 feet, Includes many high I peaks within the Yellowstone Nation- I al Park, and Is remarkable for its wild I and rugged scenery. The region Is one I of heavy snow fall, Is well timbered, and, pursuant to the wise national policy of forest preservation, Is included includ-ed almost entirely within the great Yellowstone National Forest. Just below where the two main forks of the river Join Is a narrow and deep canyon, tho almost perpendicular granite walls of which rise to a height of several hundred feet. Through this gigantic crack In the solid rock the melting snows of the entire watershed Just described find their only exit, carrying car-rying to waste during the annual flood I season of a few weeks sufficient water to reclaim many thousands of acres of the desert lands of lower altitudes. Within this canyon, at a point of almost al-most Ideal natural advantages, Is being be-ing molded the solid wedge of concrete con-crete which is to be known as the Shoshone Sho-shone dam. Tne height of this towering structure struc-ture when completed will be .'1251 feet, from lowest foundation to crest, Its length at the top from wall to wall of the canyon about 200 feet, and Us tnickness at the base 103 feet. In pfan the dam is of the arched type, wherein stability is secured by means of the form as well as tho volume of the structure. The apex of the arch being turned up stream to resist the pressure of the Impounded waters, and the foundation ami abutments literal1" dovetailed Into the solid grant, tho completed structure will form a concrete con-crete monolith of imposing propoi Ions as well as tremendous stre gt'h and stability.
