1876 
The winter months of 1876-76 were epent in Washington, 
D* 0* preparing reports of the previous field season on the 
geology ant archeology of the Cliff House legion of Southern 
Colorado, and the spring months in preparing extensive exhibits 
for the Museum to be shown at the Philadelphia Centennial, The 
summer was spent in a remarkable trip with A, D. Wilson on the 
primary triangulation of the great peaks of the front range of 
Colorado,^ .During the season we climaed eleven peaks, upwards of 
14,000 feet or approaching that hei ht, among the a ;re Ion * , 
likes, Grays, Culebra, Torrey, .Evans, Sopris, Lincoln, Grizzly, 
yhlt© Bock, lowell, Italian, Blanca, Hesperus and the quartzites, 
and, I flatter myself in making the statement, that I was the 
first to reach the summit in every case. 
The fell and winter were spent in the preparation of 
omX 
reports in elaboration of th© panoramic views made during the 
A 
summer and the current office work. The survey occupied during 
this period the Second National Bank Building on Seventh street.
