THE RECESSION OF THE GLACIERS OF 

 GLACIER BAY, ALASKA 



By Fremont Morse, U. S. Coast and Geodetic Survey 



ONE of the most interesting points 

 brought out in our past season's 

 work in Glacier Bay is the re- 

 markable retreat of the glaciers discharg- 

 ing into that body of water. The sur- 

 veys made by the Canadian parties in 

 1894 located the fronts of the glaciers at 

 that time and give us data for an accurate 

 determination of the amount of the re- 

 cession, when taken in connection with 

 our work this year ( 1907) . 



The primary cause of the changes 

 which have taken place can without 



doubt be traced to the great Yakutat 

 earthquake of September, 1899. At that 

 time an earthquake occurred which was 

 apparently central in Disenchantment 

 Bay, or the upper end of Yakutat Bay, 

 and which upheaved the rocks in that 

 vicinity, by actual measurement, some 30 

 or 40 feet. In one place it was measured 

 and found to be 47 feet. This great dis- 

 turbance of the earth's crust profoundly 

 affected the glaciers in Glacier Bay. 

 Previous to that time for many years the 

 excursion steamers of the Pacific Coast
