IO2 ALASKA GEOLOGY 



gap in the geological column heretofore inexplicably va- 

 cant. Stratigraphically it is the most important discovery 

 in geology made by the Harriman party, and Dr. Palache 

 is to be heartily congratulated on his success in obtaining 

 material by the determination of which this discovery is 

 made certain. 



Dr. Palache's party camped on the eastern side of Chi- 

 chagof Cove near the outlet of the lagoon, and the localities 

 where fossils were obtained were noted by him as follows, 

 the number preceding each note being that assigned the 

 locality in our record book. 1 



3373. Beds near the camp on the eastern side of Chi- 

 chagof Cove, belonging to what Dr. Palache has desig- 

 nated on his sketch chart as the i upper beds ' of the 

 Stepovak series. (See pages 75 and 77.) 



3374. From the west headland of Chichagof Cove, beds 

 similar to those of 3373. 



3375. From the east side of West Cove, the beds be- 

 longing to the upper series. 



3376. From the hill above the camp, the same horizon as 

 at the camp, but about a mile along the strike. 



3377. From slope of Chichagof Peak, beds belonging to 

 the ' lower ' series of Dr. Palache, near a dike. (See 

 page 74.) 



3378. From the breccia beds of the same lower series as 

 3377, on the slope of Chichagof Peak. 



That some difference in age exists between the beds of 

 the lower and upper series is obvious, but that this differ- 

 ence involves a faunal difference is not so certain since 

 several of the species found in the lower beds were also 

 collected from the upper beds, and the total number from 

 the lower beds is too small to admit of any valuable com- 

 parison being made. If any faunal difference exists it is

 Museum, at Washington, D. C.
