A short distance farther and we shoot into — 



No. 24. Tunnel No. 2, the longest on the road, 770 feet in length, cut 

 through reddish and purplish indurated clays, of the Wasatch 

 group of Miocene Tertiary. Descending rapidly we reach — 



Nos. 25, 26. Castle ROOKS, at the head proper of Echo Canon, 975 miles 

 west from the Missouri and 6,290 feet elevation. 



jSos. 27, 28. Tower BOOKS, or pinnacles upon the face of the castle. 

 The rocks bear a remarkable resemblance to some old. dis- 

 mantled fortress, with its towers, crumbling walls, and im- 

 mense embrasures. 



They are of massive red sandstone from 500 to 800 feet high, 

 which have weathered into these curiously castellated forms. 



No. 29. Pulpit Hock, at the mouth of Echo Canon, 991 miles from 

 Omaha, and 5,540 feet above the sea. The railroad sweeps 

 around it in a 'graceful curve, and so near that one 

 might reach from the car-window and touch it. The iso- 

 lated rounded mass above, which seems to stand alone and 

 almost ready to tumble into the valley below, is yet quite 

 firmly seated on its bed of sandstone. Jt is said that once 

 upon a time Brigham Young held forth to his flock from this 

 rock during their pilgrimage hither. This view shows ad- 

 mirably the coarse conglomerate or pudding-stone, charac- 

 teristic of all the Echo Canon rocks. 



No. 30. Sentinel Pock, one of the most remarkable landmarks in the 

 canon. It is a regular obelisk of conglomerate, standing 

 near the junction of Echo with the Weber Canon. It is 

 about 260 feet in height, and affords another excellent illus- 

 tration of the peculiar style of weathering, by which rocks 

 assume curious forms. This column has been very aptly 

 called the " Dog's Head,'' to which it will be seen at a glance 

 that the summit bears a resemblance. 



The peculiar form of stratification, with the varied struc- 

 ture, sometimes a firm sandstone, then a pudding-stone, is re- 

 markably well displayed in this veiw. 



The same variations of structure, on a still larger scale, may 

 be seen in — 



No. 31. The Gkeat EASTERN, a perpendicular bluff 1,000 feet in height, 

 bearing a Strong resemblance to the prow of an enormous 

 steamship. In this the inclination of the strata is well shown. 

 The base is composed of tine sandstone, running into a coarse 

 conglomerate above. 



No. 32. Looking Down Echo from above the Great Eastern, and about 

 two miles above the mouth of the canon, giving a general view. 

 On the right the high perpendicular walls, with the strata 

 dipping down westward. cleft by deep gorges, leave tho inter- 

 mediate portions standing out like huge castles, massive in 

 form and a vivid red in coloring. On the left the hills are 

 equally high, but run off into more rounded forms, and in the 

 spring-time are clothed with a bright contrasting green. 

 No. 33. A STUDY amono THE ROOKS of Echo, a mass of debris which 



has fallen from the overhanging walls. 

 >*0. 31. Tin: A ai pii i in i;a TEE, an immense semicircular wall of 1,000 feet 

 in height, three miles above the mouth of the canon, show- 

 ing the largest and most perfect wall-surface of any portion 

 of the canon. 



Leaving Echo, and turning down Weber Canon, we glide
