No. 9. Valley of the North Platte, Dear Fort Fred Steele, the 

 second crossing of the river, 696 miles west from Omaha, and 

 having an altitude of (5,840 feet. Unlike itself out upon the 

 plains, it is here a deep, clear, cold stream, not far from its 

 sources among the perpetual snows of Long's Teak. 



No. 10. Green River BUTTE, near view. 



No. 11. Green River Butte, from across the river. 



No. 12. Tea-Pot Rook, near Green River Station. 



Xo. 13. Giant's Club, near Green River Station. 



No. 14. BOOK Forms, near Green River Station. 



No. 15. Petrified Fish cut, near Green River Station. 



No. 16. Burning* Bock cut, near Green River Station. 



Views along the West bank of Green River bet ween the 

 Station and Burning Rock. The above group (10 to 20) rep- 

 resents the curious and unique scenery of Green River at the 

 point where the railroad crosses it 845 miles west from Oma- 

 ha and 6, 140 feet above tidewater. 



The formation which gives this region its characteristic 

 features is known as the Green River shales, from the sedi- 

 ments being arranged in regular layers, mostly quite thin, 

 but varying from the thickness of a knife-blade to several 

 feet 



This laminated character, with the variations in shade and 

 color, give to the hills the peculiar banded appearance, as 

 shown in all the pictures of the above series. 



In 10 and 11 we have the Castellated Butte, so prominent 

 a landmark to all travelers, having an elevation of some 800 

 feet above the river. The upper portion, or Castle, is 200 

 feet high. Nos. 12. 13, and 14 are excellent examples of the 

 curious ami fantastic shapes Which the shales have assumed in 

 the process of weathering, suggesting the titles which have 

 been given them. They have an average height of 200 feet. 

 No. 15 is so called from the thousands of perfect and beau- 

 tiful impressions of lish which are shown on the thin slabs of 

 shale; sometimes a dozen or so within the compass of a 

 square foot. Impressions of insects and water-plants are 

 found, and also a remarkable specimen of a feather of a bird. 

 No. 10 is a view a short distance west of the preceding 

 ones, where the road is cut through thin layers of a sort of 

 cream-colored, chalky limestone, interspersed with layers of 

 a dark brown color, so saturated with petroleum as to burn 

 with a good deal of freedom. This cut is called the Burning 

 Rock, from the fact that during the progress of the work the 

 rocks became ignited and burned for some days, illuminat- 

 ing the labors of the workmen by night, ami filling the val- 

 ley with dense clouds of smoke by day. 



The remaining views are glimpses along the west bank of 

 Green River between the places described above, showing to 

 good advantage the wall like and castellated forms on the 

 opposite side of the river. 



Nos. 21, 22. WasATOH,XJtAH, 966 miles west from Omaha, altitude 0,879 

 feet, on the divide between Echo Canon and Bear River. ' 



From this point the descent is very rapid into the famous 

 canon. Two miles farther on we come to and pass slowly 

 over an immense trestle-work, as shown in — 



No. 23, being 450 feet long and 75 feet high.
