187 2 SERIES. 



Before the whole party had gathered together in the rendezvous camp 

 at Ogden, (Jtah, two side trips for views were made by the photograph- 

 era — one along the foot-hills of < 'olorado, as far south as Pike's Peak, 

 and the other to Cottonwood Canon, south of Salt Sake City. Starting 

 from Ogden the 24th of June, we have views of the route through 

 Malade Valley, and Portneuf Canon to Fort Hall. Idaho. The Great 

 Teton Range, near the head of Snake River, was reached in the latter 

 part of .Inly, and worked np in detail daring a layover of ten days. 



The geyser basins on the head of the Madison were reached via 

 Henry's Lake and Tyghee Pass, and the result of a week's sojourn is a 

 large series of exceedingly interesting views of that remarkable region. 

 The falls, canon, and mammoth hot springs of the Yellowstone were 

 then re-visited for the purpose ol extending and perfecting our series. 

 The grand and beautiful scenery of the (lallatin .Mountains and the 

 West Gallatin River were next worked up, presenting to the world for 

 the firs! time some of the finest and most picturesque views in the 

 Pocky .Mountains. 



The work of this season includes forty-five, 11x14 views, the very 

 first plates of this size ever made in the Rocky Mountains, one hundred 

 and sixty, 8 x 10, and one hundred and forty live stereoscopic* 



With Imt very few exceptions the following, as also the preceding 

 views, are the first ever made of the different subjects: 



1 1 x It. 



No. 1. Camp of the United States geological survey, at Ogden. 

 Utah. (See No. KiO.) 



No. 2. Group of the members of the survey at the camp at Ogden. 



No. 3. Camp of the SURVEY at Port Hall, Idaho. (See Nos. 177 

 and 312.) At this point the wagons, and all extra baggage 

 were left behind, and the remainder of the journey effected 

 with pack-animals. 



No. 4. Group. Headquarters tent, of the Snake River division. 



No. 5. MOUNT HAYDEN, OR THE GREAT Teton. The highest peak in 

 the Great Teton Range, near the head- waters of Snake River, 

 and lying upon the boundary between Idaho and Wyoming. 

 It has an elevation of 13,833 feet above the sea, about 6,000 

 feet above the canon shown in the view at the foot of the 

 peak, and over 7,000 feet above Jackson's Lake, which stands 

 under it on the opposite side. Our view is from the east, 

 looking directly west. Although not the highest, it is the 

 grandest and most alpine like peak in the West. No others 

 can show such abrupt angles and bold outlines, where snow 

 even can rest only in small patches on the ledges. It gathers, 

 however, in great masses in the bottom of the great canon at 

 our feet, 2,000 feet b>'low. So far as known, it was ascended 

 tor the fust time by Messrs. Stevenson and Langford, on the 

 29th of duly, 1872. A full account of the exploit occurs in 

 Scribner's Monthly for June, 1873.
