OBSERVATIONS MADE IN 1900 ON GLACIERS IN BRITISH COLUMBIA. 

 BY GEORGE AND WILLIAM S. TAUX, JR. 



While the glaciers noted in the following report form but a small 

 fraction of the hundreds in the Rocky Mountains of Canada, their 

 continued recession may be taken as an indication of the changes 

 which are taking place in the glaciers of the region, A moderate 

 winter, followed by an early and warm spring melted the snow and 

 flooded the rivers at an early date. The continued wet and stormy 

 weather, which extended far into the spring and summer, did 

 much to increase the amount of melting. So far as it has been 

 possible to determine, all the glaciers of this region are still reced- 

 ing. One exception to this rule was reported, but the advance 

 could not be proved with any certainty. ^ 



Victoria Glacier. 



The rocks marked last year to determine the motion and shrink- 

 age of this glacier were again noted on July 24, 1900. The large 

 block of limestone about one mile from the tongue marked " VX 

 '99" appeared to have moved 147 feet, while a large block of 

 sandstone near the terminal moraine had an apparent motion of 

 115 feet. The general condition of the glacier appears practically 

 the same as last year. Measurements taken on the northwest side 

 indicate a shrinkage of about six feet for the year. Several very 

 fine glacier tables were noted, one being a block of sandstone 

 eighteen inches thick, from ten to twelve feet in diameter, and 

 elevated not less than five feet from the surface of the surround- 

 ing ice. 



AsuLKAN Glacier. 



This glacier has receded perceptibly since last year, the tongue 

 being twenty-four feet further up the valley than when last noted. 

 There has also been a marked shrinkage in everv dimension.
