MMOEAHIXJM BHJAHDITO THE ACOOMPAKYliKr MAP 
Owing to the fact that full circles of pictures were taken at only three 
points (Logan, Mattouisse, and Collins) and these three points lie nearly in 
one line (all the prominent peaks are along the same general line) it was 
impossible to use the views effectively for triangulation purposes, consequently 
this map should be regarded as a plan constructed from a very incomplete series 
of photographic elevations, taken at points not definitely located, in other 
views. She contour lines represent very roughly 100 ft. elevations. The writer* 
as you know, did not see some of the areas mapped* Other members of the party 
did 3 ee some of these areas as well as others not her© mapped. A map constructed 
from such sources of information must necessarily contain very many errors. 
This preliminary photostat copy of the map is sent to you with the special 
request that you go over it as carefully as your available time will permit, 
and make such changes as you think necessary (preferably with colored Ink or 
pencil) in any manner that is intelligible on the mg£, and return the same to 
me as soon as convenient. From the corrected copies a new map will be constructed 
embodying all corrections, in so far as they are not inconsistent with each 
other and with the few points definitely determined by photographic triangula¬ 
tion. 
All the names on the map are those generally used on the trip, or later 
suggested by Prof. Feraald or Dr. Podge— (excepting only the name "Dodge”). 
In going over this map please consider names, distances, contours, brooks, 
* 
elevations, etc., etc., and make as many changes in the map as you may deem 
necessary before returning it.
