No. 144. A view of the OOAL-BEARING bluffs near Point of Rocks, 

 on Bitter Creek, Union Pacific Railroad, 805 miles west of 

 Omaha, and 0,400 feet above the sea. The veins are about 

 live feet thick, cropping out high on the bluff, and with a very 

 slight inclination to the northwest. 



No. 145. Camp on the Forth Fork of the Platte. 



No. 140. Bluffs on the North Fork of the Platte, near the 

 crossing of the old overland stage-road. They are eighty to 

 one hundred feet in height, extending along the east bank of 

 the river, and composed of a grayish-brown sandstone, ex- 

 hibiting in a remarkable manner the various signs of shallow 

 water depositions, ripple, rain, and mad markings. Broad, 

 flat masses of rock lie at the base of the bluff, fifteen or 

 twenty feet square, with the surface covered with these 

 peculiar markings. 



No. 147. A view on the MEDICINE Bow River, on the line of the old 

 stage road. Elk Mountain shows dimly in the background, 

 through a snow-storm, which was prevailing at the time our 

 view was taken. 



Elk Mountain is the northern spur and highest peak in the 

 Medicine Bow Range. Elevation, 7,152 feet above the sea. 



No. 14S. Camp on Rock Creek, showing a glimpse of Bock Creek 

 Canon and the snow-clad spurs of the Medicine Bow Mount- 

 ains. 



No. 140. Camp FAREWELL, at Fort Sanders, so named as being the last 

 regular camp of the survey of 1870. Showing merely a few 

 of the members, the tents, and animals of the expedition. 



No. 150. The ROBBER'S Roost, at Virginia. Dale, a stage-station on the 

 line of the old overland route, and which attained an unen- 

 viable notoriety during I860 and 1863, while kept by Jack 

 Slade, a noted desperado of that time. 



No. 151. PLATTE Canon. A view from the plains, looking up into the 

 canon, being the exit of the South Platte from the mount- 

 ain range that separates South Park from the plains. A 

 rugged, precipitous, and inaccessible gorge. 



No. 152. Rocks below Pi. atte Canon. A remarkably expressive view 

 of the upheaved red sandstone, worn by atmospheric agen- 

 cies into most wonderful forms, the strata standing up at an 

 angle of 60 degrees, and weathered out into a thousand 

 curious pinnacles and serrated ridges. 



No. 153. Pleasant Park, a small picturesque valley, lying between 

 the sandstone ridges ami the mountains near the Colorado 

 divide. 



No. 154. Soda Spkings, on the Fountain qniBouille, three miles above 

 Colorado City. At the present time (1873) the springs have 

 become a fashionable watering-place, and the encroachments 

 of civilization have nearly obliterated the old natural fea- 

 tures of the locality. 



No. 155. Ute Falls, in Ute Pass, where the Fountain qui Bouille is 

 forced through a narrow, precipitous gorge, about one mile 

 above the springs. Now, these falls are searcelv distinguish- 

 able, as a road has been blasted through the massive granite 

 that forms the walls of the canon, and the accumulation of 

 debris falling into the stream, has changed its character en- 

 tirely.
