NOTES ON AN ESKER — BY D. S. MCINTOSH, B. A., M. SC. 141 



to the east. Wild animals have made a path along the summit. 

 To the west at the furthest point explored, it is lost in an enor- 

 mous mass of angular granite boulders. Mr. Spurr states that 

 the esker extends for twenty miles or so across the country, and 

 that to the south there are two similar ridges that appear to 

 join the main esker at an angle from about southwest. 



The time spent in exploration and examination was not 

 sufficient to arrive at anything of scientific interest except the 

 location of the esker. It is hoped that an opportunity may be 

 had to again visit the locality and find out something about the 

 ice movement at this point and the cause of the presence here of 

 this glacial deposit, and to visit the similar deposit that runs 

 east from Hectanooga station towards Blue Mountains. 



It was rather an unusual occurrence while in a wilderness 

 country, to have an aeroplane pass and re-pass directly over- 

 head. The return trip was uneventful, other than that the 

 writer came within an ace of upsetting the canoe, and that 

 the canoe ran upon a submerged boulder in the middle of a 

 lake and remained fast for some minutes.
