On the western side of the stream, a gigantic boulder was found, marked with the legend, "Sr., A, 8|17|'04. To ice 79.4 ft." The marks and measurement were made by Dr. Sherzer in 1904. A measurement now made to the nearest ice gave 79.6 feet, showing that the ice was, practically, in the position it had occupied when the previous measurement was made.

The accompanying map of the tract here referred to as the Wapta icefield is copied from a topographical map of the Yoho valley section of the mountains, now in course of preparation from Government photographic surveys, and is reproduced by permission of Dr. E. Deville, Surveyor-General of Dominion lands.
