Abstract

DR. WRIGHT, in his “Ice Age in North America,” has calculated that the Muir Glacier erodes its bed annually to the depth of one-third of inch (p. 64). and Prof. Harry Fielding Reid, in his very interesting “Studies of the Muir Glacier” (American National Geographical Magazine, March 21, 1892, p. 51), arrives at the still more startling result of three-quarters of an inch per annum. As one who has paid some attention to rates of denudation by various eroding agencies, I felt some curiosity to know in what way these figures were arrived at. I find that these two calculations are substantially the same, the difference arising from Prof. Reid crediting the whole of the erosion to the glacier bed which occupies only half of the watershed of 700 square miles.
