on this part of the climb. The final scramble was easy. On 

 reaching what we had believed from below was the summit 

 of a peak, we were surprised to find that it was merely a 

 promontory between two gullies, jutting out from a wide, 

 undulating area of snow, or rather of ice, with a snow blanket 

 upon it. The ice-sheet, several square miles in area, sends 

 Glacier tongues down many short valleys and gullies. It 

 was the feet of these we had been crossing between Bolter 



MOUNTAINS NEAR ADVENT VALE.

 we made 

 the entire 

 tour of the 

 mountain 

 mass, by 

 crossing Fox Pass, descending Plough Glacier, and return- 

 ing by Bolter Pass. Standing here on the bluff, and looking 

 across Advent Vale, it was easy to perceive how the plateau 

 behind had once formed part of a wide-extending flat, which 

 had been elevated and cut down into many valleys by streams 

 eating their way back into it. We were, in fact, on what 

 I have called the lower plateau, looking edgeways along it. 

 In various directions we could see the remnants of the upper 

 plateau standing upon it in the form of rounded snow-covered 

 hills, such as Mounts Lindstrom and Nordenskjold.
