beach exists. The whole soil seems of the sane general nature, sone 

 in lurips or boulders, the other in gravel sand, or solidified poT7der. 

 To KO the outstanding foatures of Bogoslof are: 



1, The apparent solidity of Castlo Roclcs, 



2, The diirension in size of Grewingk (It is no noro than one-eighth 

 its 1906 size) , 



3, The fact that Grov/ingk is merely a huge pile of rock (held to- 

 gether by loose lava) gradually falling vrith the sea, 



4, The fact that the edge of the crater, is, as always, concave to 

 the southwest, 



5, Tlie general appearance of permanence. 



6, The impression that the "pushed up" sea botton forms the island 

 proper, 



7, Tlie decrease in the number of birds and sea lions, 



8, The appearance of erosion on Castle Rocks, 



9, The apparent lack of change in souading a few hundred yards off, 

 10, The change in the direction of the eastern edge of the crater. 



My present tour of duty in Alaskan waters is about over, I 



don't know whether or not I shall ever come again. Should I come - in ■ ■ 



what guise will Bogoslof present itself? No conjecture is safe. Of 

 one thing only will I bo sure and that is - change," 



EEPORT OF COM/iAITOnTG OFFICER, CAPTAB^^ J.T.JiOTTE L. NORTHTa/JTO. 27 SEPT,. 1927 . 



"On September 27, 1927, the HORTtlKJMD enroute to the Pribolof 

 islands stopped off Bogoslof Island to investigate a report that the 

 Island was showing new activity, 



"The observations showed: 



(1) That in place of two islands, Castle Eock and G-rcvj- 

 ingk, or Fire Island, as last reported there now 

 existed only one island. Castle Rock and Grewingk 

 wore now connected by a long sandpit. Previously 



a deep channel v;as reported between these islands, 



(2) That groat activity had taken place and was taking 

 place on Bogoslof Island, A new mound had risen 

 about 175 feet above the plane cf the island in 

 the approxiiriite forr.:er positions of Metcalf Cove 

 and McCulloc^;: Peal^, A groat anoujit of stcan v;as 

 coming out or this new mound or cone," 



REPORT OF CO]\/[MAMDER C, DEMCH. U.S.C.G.C. TAIXAPO'OSA, 1931 . 



"Left Nikolski at 8:05 p.m, 6 June and arrived off Bogoslof Island 

 at 6:30 the next morning, A landing party examined tho island carefully and 

 made a running survey of the land area. TBmperatures in the lake were fomid 

 to range from 64° to 144"^ Falironheit, and the v;ater is salty. The lake ap- 

 pears to have the saire level as the sea, Tiio lava bod, from Tjhich stcan is 

 now being emitted, is plainly older than the lava at Gar-elol, It was jagged, 

 however, and one needs to exorcise caution in climbing up there. It is 

 always possible that a fairly heavy piece of rock r.ay be so poised as to 

 fall with a man's weight upon it. The lava area was climbed nearly to its 



-63'--
