lo 



red beds at right angles, forming a regular gorge, with walls 

 — — from 50 to 150 feet in height. 



At the head of this gorge the stream has at some time 

 changed its bed, passing directly through a point of rocks 

 that extend across the channel. The old bed is now over- 

 grown with trees and bushes, but is 50 feet higher than the 

 present one. The stream must have changed its course, 

 bringing its waters against this rock, and, finding a fissure 

 opening through it, gradually wore its present channel. 



Jt is as perfect a bridge as could be desired. The opening 

 beneath is about 150 feet wide and 50 feet high. 



The arch above forms a perfect span from a great tower on 

 one hand to the old bed of the creek on the other. 



.No. GS. Fort Fetterman, nanted for Bvt. Lieut. Col. YVm. I. Fet- 

 terman, killed at the Fort Phil. Kearney massacie, December 

 21, 1866. 



Established July 1!', 1807, and garrisoned by four compa- 

 nies of infantry. Is situated at the mouth of La Frele Creek, 

 1.15 miles north from Cheyenne, and 70 miles from Fort Lar- 

 amie. 



No. G9. Fort Laramie, named after an old trapper, was established 

 in 1849, and was once a trading post of the Northwestern 

 Fur Company. It is noted as being the place where many 

 important treaties have been made with the Indians. Situ- 

 ated on the Laramie Liver, about two miles above its junc- 

 tion with the North Platte, and on the line of the old over- 

 land road to Oregon and California. 

 '\ No. 70. Camp on the Lok ELDER. Twelve miles west from Fort 



* Fetterman, and but a short distance above its junction with the 



1 Matte. Contrasting well with the rugged features of the 

 ridge are the terrace-like benches or tables, remnants, prob- 

 ably, of some higher levels not swept away. 



Nos. 71, 72. Box Elder Canon affords a good section through the main 

 ridge, being a much more regular gorge than the canon of 

 the La Frele. 



It is from 000 to 800 feet in depth, entirely of erosion, and 

 so narrow that it is difficult to pass through it on foot, the 

 side walls being perpendicular and sometimes overhanging. 

 The predominating rocks are calcareous sandstones and 

 some layers of (pate line limestones, with a great variety of 

 texture. 



No. 73. Camp on the North Platte, near old Fort Caspar, thirty- 

 four miles from Fort Fetterman. 



No. 7-4. Bad Lands, near Caspar .Mountain. There is here a consider- 

 able area covered with light gray sandstones, which have 

 weathered into most unique forms. They resemble the ruins 

 of some old village, portions of the stone walls, with the chim- 

 neys, remaining. 



No. 75. View from Caspar Mountain. This mountain is an immense 

 table that has been lifted nearly horizontally out of the plain 

 some 800 or 1,000 feet. Our view is taken from it, looking 

 out upon the plains toward the Platte, showing the gradual 

 dying away of the hog backs and terraces into the level valley. 



No. 70. BED BtJTTBS and the North Platte River. 



No. 77. Camp at Red BUTTES. Our camp at. the Led Buttes was 

 pleasantly located on the broad grassy bottoms of the Platte,
