60 GEOLOGICAL NOTES ON KOSCIUSKO, 



Muniong (Australian Alps, authors), viz., that of Antuco in the 

 southern part of Chili, in lat. 37° 40'^ on which snow lies at the 

 height of 7,960 feet, yet even this is far higher in proportion 

 than the snow of Kosciusko" (3, p. 225). 



If further observations be omitted (including Baron ISTorden- 

 skj old's preliminary report in "Die Geographische Zeitschrift" for 

 1896) down to within the last few years, we find a summary of 

 his observations in the work noted below, in which he compares the 

 glacial deposits of the Magellan region to the boulder-cla}^ of 

 Europe.* 



The same author states in another paper f (p. 408), " Here also 

 (in the neighbourhead of the Gallegos Valley, authors) in the 

 neighbourhood of the large depression occupied by the muddy, 

 brackish water of the ' White Lake,' Laguna Blanca, and from 

 there eastwards to the Straits, we find the curious, steep, lofty 

 hills composed of boulder clay, which I observed first in Terra 

 del Fuego, and which are so characteristic of the formerly 

 glaciated territory in this region." 



Mr. J. B. Hatcher has also described the Magellan glacial 

 deposits. I 



Referring in a later paper to Mr. Hatcher's observations, 

 Nordenskjold makes the important statement§ that as regards 

 the age of the Magellan glacial deposits, Hatcher collected some 

 molluscan shells from the Cape Fairweather beds, and Pilsbry 

 has determined these shells to be not older than Pliocene. It is 

 also stated that these shells underlie the oldest glacial deposits 

 of the Magellan Territories.
