GREAT EARTHQUAKE OF SEPTEMBER TENTH 369 



During this same period from 1899 to 1907 Grand Pacific Glacier had 

 retreated 8% miles and the other ice-tongues of Glacier Bay smaller 

 amounts.®^ Since Mr. Buschmann has testified that the increased flow 

 of icebergs began with the September 10 earthquake, we may safely 

 ascribe the initiation of the rapid retreat and loss of scenic beauty of the 

 Muir Glacier to this shaking in connection with the Yakutat Bay earth- 

 quakes. 



Canadian Coast Range. — At Atlin and Discovery City, British Colum- 

 bia, in the Canadian Coast Eange, about 215 to 230 miles east of Yaku- 

 tat, the severe earthquake was felt in several mining camps on September 

 10,^* as well as at the Hudson Bay post near Teslin Lake,^^ 275 miles 

 east of Yakutat Bay. 



On the southeast shore of Atlin Lake, Prof. J. C. Gwillim, of the 

 Canadian Geological Survey, made the best of these earthquake observa- 

 tions.^® The shock came at 12.45 p. m., local meridian time, corrected 

 by a latitude observation on the sun at noon on that day. There was an 

 undulating motion lasting about 30 seconds. Water was spilled out of 

 small utensils being used at dinner. There was a heavy wind, so no 

 earthquake water waves could have been detected on Atlin Lake. 



In the Surprise Lake district, east of Atlin, British Columbia, there 

 were earthquake shocks during the first half of September, 1899, the 

 heaviest shock coming on September 10. Mr. John Bimms®^ observed 

 what he interpreted as smoke from a supposed volcano, but what may 

 have been dust from great avalanches in this part of the Canadian Coast 

 Pange. Certain glaciers were broken. 



Lynn Canal. — At various points along this fiord and in the mountains 

 near by, the great earthquake of September 10, together with those of 

 the preceding Sunday, was felt by a great many people. Since Skag- 

 way, Haines Mission, Dyea, Pyramid Harbor, and Juneau are steamer 

 landings, and as Skagway was connected by telegraph with Vancouver 

 and Seattle, these observations were reported in a great many news- 

 papers. The accounts®^ are of variable completeness and accuracy.
