Might have run across the map mentioned in W. M. Camp's book:

3. Walter Camp prepared several maps pertaining to the Little Bighorn River fight, one of which is a large table-size map in several sections. The identifications in this Curley narrative are not shown in the Camp map illustrated in this book. Camp uses the terms Reno peaks, Edgerley peaks, and Weir peaks interchangeably.
