E. PHOTO TAKEN JULY 4, 1907, WITH THE PEAKS BEARING SOUTHWEST 



1. McCulloch Peak. 2. Perry Peak. Two months after these photos were taken 

 McCulloch Peak exploded and its ashes were scattered on the islands to the southeast for a 

 distance of 70 miles. At Unalaska, 60 miles away, there fell 3/16 of an inch in one hour, 

 then followed a fierce rain. Photos from Capt. F. M. Munger. 



The navigator of the Rush made a 

 ■survey of the harbor and found it to be 

 about one mile across, with from four 

 to twenty-five fathoms of water; black 

 sand bottom ; temperature of water, 46 

 F. The shore to the south of the harbor 

 was steaming (photographs C, F., and 

 sketch ) . 



9. In September, 1908, the McCulloch 

 visited the island and found the south- 

 west portion smoking; shoals had made 

 out from the northeast and east sides, 

 and patches of discolored water were ob- 



served to the north and northwest. Bad 

 weather and rough sea prevented further 

 survey. 



10. The following relative to forma- 

 tion is quoted from the report of First 

 Lieutenant B. H. Camden, U. S. R. C. S., 

 who surveyed the island July 4, 1907: 



"The formation consists of disinte- 

 grated rock, basalt, feldspar, scoria, tufa, 

 pumice, obsidian, trachyte, other igneous 

 rock, and volcanic mud, all more or less 

 discolored with a deposit of sulphur."
