GEOLOGICAL AND ARCHAEOLOGICAL SURVEY OF SOUTHWEST COLORADO, 
HAYDEN SURVEY OF THE TERRITORIES, 1875 , 
The season's field work began at La Plata eainp, San Juan 
County, Colorado, Tuesday, July 27, 1875. I started the train 
this morning with thirty days' provisions. .. Our intention was 
to go direct to Ute peak, thence to the west and south. Jackson 
(W.H.) marches with us for some days. He is on his way to the 
Moqui (Hopi) country, and intends to he out some five weeks. 
Mail was expected this morning and we concluded to wait until 
afternoon. Mr. Charles Aldrich is to go with us to Ute Peak 
and then return. No mail received at 3:00 o'clock and Jackson 
and Aldrich remained to get it in the morning. Made Maneos 
camp July 28th. 
* 
Left Mancos camp with the intention of marching about fifteen 
miles to the west but found no water until we reached the base of 
Ute peak, a distance of thirty-five miles. Encountered Nara 
Guinnep's camp at about 5:00 o’clock. An old man called "How- 
do-do Bueno" pointed out a spring to us - a very weak and obscure 
one - the only water in the neighborhood. Without the Indian’s 
advice we should probably have had a dry camp. 
Cretaceous rocks only are exposed along the trail. Five 
miles from the Mancos we passed the divide into the McElmo. The 
inoceramus limestone is exposed near the divide. On the left 
rises the escarped cliffs of Mesa Verde. The lower slopes for 
800 or a 1,000 feet are of the upper cretaceous shales, then 
My numerous panoramic views were in long books and were 
turned over to the new Geological Survey.
