entirely of soft red shale with some beds of sandstone. Beyond 

 milepost 681 this sandstone has been extensively quarried for build- 

 ing stone in Salt Lake City, but the growing use of cement has led 

 to the abandonment of the quarries. 



Spanish Fork is here joined by Diamond Fork, a stream coming 

 from the northeast (right), which, though rather small, has been 

 utilized by the United States Eeclamation Service to bring water 

 from Strawberry River, a tributary of Green River, through a divid- 

 ing ridge, to irrigate some barren land in Salt Lake Valley.^® The 



FiGTRH 59. — M;ip of Strawberry Valley reclamation project. The dash line shows the 

 boundary of the Green River drainage ba.sin. 



water obtained by damming Strawberry River is carried through 

 the ridge by a long tunnel and discharged into one of the head 

 branches of Diamond Fork. From this point it flows by gravity 

 into Spanish Fork and is diverted lower down, where it is most 

 needed. The traveler may see the diversion canal near the lower 

 end of the canyon. 



'*The Strawberry Valley diversion 

 (see fig. 59) is one of the large proj- 

 ects that the Un?ted States Reclama- 

 tion Service has carried to a successful 

 completion. By this project water that 

 is not needed where it falls is taken 

 over into andther drainage basin and 

 given to the thirsty land. As shown on 

 the map (fig. 59) Strawberrj' River is 

 one of the head branches of Duchesne 



River (du-shayne'), a stream that en- 

 ters Green River from the west. 

 Strawberry River beads in rather open 

 country near the Wasatch Range, 

 whicli has an average elevation of 

 about 8,000 feet above sea level. At 

 that altitude the cultivation of any but 

 the most hardy grains and vegetables 

 is impossible, so that the water is of 

 little value where it falls, but over the
