Owing to the fact that full circles of pictures were taken at only three 
jy 
points (Logan, ’.lattouisoe, 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. The contour lines represent very roughly 100 ft. elevations. The writer, 
as you know, did not see some of the areas ;;»apped. Other members of the party 
did see some of these areas as well as others not here 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 tbat will permit, 
and make such changes as you think necessary (preferably with colored ink or 
pencil) in any manner that is intelligible on the map , and return the same to 
mo 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 
otter end with the few points definitely determined by photographic triangula¬ 
tion. 
All the names on the map a e those generally used on the trip, or later 
suggested by Prof. Fernald or Dr. Dodge—(excepting only the name "Dodge")* 
In going over this map please consider names, distances, contours, brooks, 
elevations, etc., etc., and make as mm .y changes in the map as you stay deem ' 
necessary before returning it.
