GEOLOGICAL SOCIETY OF WASHINGTON 



The 327th meeting of the Society was held in the lecture room of 

 the Cosmos Club on April 10, 191 8. The regular program was as 

 follows : 



Edwin Kirk: Paleozoic glaciation in southeastern Alaska. During 

 the past field-season a tillite of Silurian age was found in south- 

 eastern Alaska. Kosciusko and Heceta Islands, where the best Silurian 

 glacial deposits are to be found, lie between 55° and 60° north latitude 

 and 133° and 134° west longitude. These islands are situated on the 

 west coast of Prince of Wales Island, toward the northern end. The 

 most favorable locality for ah examination of the conglomerate is in 

 the large bay about midway on the north shore of Heceta Island. 

 The coast here is well protected from storms and there is a continuous 

 outcrop of the limestone underlying the conglomerate, the conglomerate 

 itself, and the overlying limestone. In places the conglomerate is well 

 broken down by weathering, making the collection of pebbles and 

 boulders an easy matter. As exposed, the beds outcrop along the shore 

 between tide levels, and give an outcrop perhaps 2,000 to 3,000 

 feet in length.
