NINTH ANMJAL REPORT OP THE UNITED STATES 
GEOLOGICAL AND GEOGEAPHICAL SURVEY OP THE TERRITORIES, 1875. 
By P. V. HAYDEN. 
"The Upper San Juan, Mesa Verde, and El Late regions came 
within the area assigned Mr. W. H. Holmes, who, in addition to 
his geological investigations, made a special examination of the 
archeology of the region, bringing out with his ready and artis¬ 
tic pencil even more wonderful ruins (of the same general class, 
however) than were found by Mr. Jackson the season previous." 
(page 12-13) 
Pages 13, 14, 15 & 16 are devoted to a review of Holmes' 
work by Dr. Hayden. Also mentioned on pages 23 and 24. 
Holmes' report on his survey of the San Juan Valley, Geolo¬ 
gy and Archeology, occupies pages 237-239. 
"The occasion of the display at the International Exhibition 
at Philadelphia led to a desire to represent as forcibly as possible 
some of the recent discoveries of the Survey of remarkable ancient 
ruins in Southwestern Colorado, and the success of Mr. Holmes with 
the Elk Mountain models suggested the same means for effecting 
this purpose* There are six now completed of archaeological sub¬ 
jects, as follows 
The Maneos Cliff House, by Mr. Holmes, represents a ruin 
in an exceedingly well preserved condition, perched upon a little 
shelf, or niche, in the face of a bluff, 800 feet vertically above 
the valley below. The model is 30 by 40 inches in dimensions, and 
the scale four feet to one inch.* (page.23) 
"The Great Triple Walled Tower, on the McElmo, by Mr. Holmes, is 
a horizontal model thirty inches square, representing, on a scale of 
four feet to one inch, the ruins of an exceedingly interesting cir¬ 
cular stone tower in Southwestern Colorado.” (page 24)
