Mounts Victoria, Lefroy, and Aberdeen, and except in its upper 

 portions, the glacier is covered with debris. The glacier is nearly- 

 flat, and each of its upper ends entirely fills its valley. Snow^ and rock 

 from avalanches form a heterogeneous pile on the surface, snow 

 predominating at the ends and the sides of the upper portions. 

 This snow is rapidly melted by the heat of the sun, and a short dis- 

 tance from the upper ends is a region of small ice pillars. As the 

 lower end is approached, surface debris increases, until at the extreme

end it is in most places impossible to tell where the ice ends and 

 moraine begins. 



In recent geological time this glacier was evidently of much 

 greater extent, but in the immediate past it extended only a short 

 distance farther than at present. It has left a series of recessional 

 moraines, but these are close together, often crossing or ramifying. 

 Closely bordering this recessional belt are fair-sized trees, and beyond 

 these trees no moraine is found. Glacial material is abundant 

 throughout the valley, but beyond the moraines it is in a secondary 

 position, deposited by water. Of late, therefore, the glacier has 

 retreated but little.
