70 UNIVERSITY OF COLORADO STUDIES 



Boulder, have just been discovered; all suggest that there are numbers 

 of other glaciers tucked away in the more inaccessible mountain 

 fastnesses of Colorado — perhaps some which are larger and more 

 interesting than the largest thus far discovered. However, let us 

 hope that the name may not be appHed to neve remnants such as are 

 now popularly called glaciers in various localities. 



Bibliography 

 This bibliography includes all the papers known to the author which bear 



directly upon glacial phenomena in Colorado. As an aid to students a number 



of important papers discussing glacial phenomena in general and especially existing 



glaciers outside of Colorado in North America have been added, including all 



papers cited in the text of the present report. Information concerning omitted 



papers would be gratefully received, to be incorporated in some future supplement.
