Xo. 6. The Three Tetons, upright, including a narrow angle of view. 

 Xo. 7. The Three Tetoxs. oblong, including a wide angle of view. 



Views from one of the summits of the limestone ridges 

 which form the western foot hills of the Teton Range, and 

 at an elevation of 11,500 feet. This is the average height of 

 the range, only the "rami peaks in the distance rising above 

 it. We look directly east over a broad, snow covered plateau 

 four miles wide, and just at the foot of the Tetons is the 

 Grand Canon, 2,000 feet below the surface. No. 5 was made 

 from the other side of the small butte that lies direct lv under 

 the Middle Teton. 



Nbs. 8, 9. Panoramic view in the Teton Bangs, looking east and 

 south, including a view of about 120 degrees. No. 8 is the 

 same as Xo. 7. Xo. looks south over the West Teton 

 River, and up its right-hand fork. On the right-hand side of 

 the canon is an exposure of over 2,000 feet of limestone, very 

 nearly perpendicular. The distance rolls away into the per- 

 petually snow-covered plateau of the Summit Range. 



Xos. 10, 11. Camp at the foot of the Three Tetons. in the Teton 

 Basin, and ten miles in a direct line from them. Elevation of 

 cam]), 6,646 feet, Mount ilayden, the highest Teton, rising 

 7, 1ST i'eet above it. 



Xo. 12. Group of all the members of the United States geo- 

 logical survey. A simultaneous meeting of all of the 

 divisions on the 15th of August, including sixty-two persons 

 in all. 



Xo. 13. I'PPKK Fire Hole Basin, from the crater of Old Faithful, a 

 general view, looking down. In the middle distance is the 

 Grand Geyser in eruption, and at the left is the Castle. 

 Within the scope of this view are all of the largest and most 

 active geysers. (See No. 439, page 44.) 



Xo. 14. ORATER of the Castle Geyser and the Beautiful Hot 

 Spring. Upon the west side and midway in the Upper 

 Basin. A castle-like form, built up to a height of forty 

 feet by the deposition of the silica held in solution in the 

 hot waters of the geyser. The eruptions a re of long duration, 

 lasting sometimes two and three hours, attaining a height of 

 one hundred to one hundred and fifty feet. 



The circular hot spring in the foreground is about twenty- 

 five feet in diameter, funnel-shaped to a depth of forty-feet, 

 with a beautifully-scalloped border, one foot in height, and 

 most delicately tinted in red and yellow, upon a white ground. 

 The water is of a most perfect cerulean blue, shaded from an 

 almost black center to lighter and more delicate hues in the 

 more shallow portions. (See Xo. 295, page 32.) 



Xo. 15. Crater of the Grotto Geyser, situated near the lower end 

 of the Dpper Basin. An irregular mound, full of sinuous 

 orifices, from which the water is projected in all directions 

 during eruptions. The eruptions are quite numerous, going 

 off nearly every three hours, each one lasting about fifteen 

 minutes. (See also Xos. 207 and 20S, page 32.) 



Xo. 1G. Crater of the Architectural Geyser, in the Lower Basin , 

 showing the central portion only, of a total width of about 

 sixty feet. The circular orifice from which the geyser issues 

 is about twelve feet in diameter. It is constantly boiling.
