LYNN CANAL 
II 
at the foot of a mountain range, resembling a continental 
glacier in its mode of wasting, but distinguished by the 
fact that it is fed by the alpine glaciers of the mountain. 
An alpine glacier may be simple and separate, or com¬ 
pound. Two or more often descend from the same neve. 
Still more frequently two meet and coalesce after the 
manner of rivers, and a trunk glacier may have many 
tributaries. Small alpine glaciers are sometimes called 
glacierets , or, if visible high on the sides of mountain 
valleys, hanging glaciers. 
For the purpose of the present report it is convenient to 
distinguish glaciers which reach the sea and discharge 
bergs, from those which end on the land. Reid calls 
these, severally, tide-water and alpine glaciers; 1 and 
they have also been called (after whose initiative I do not 
know) live and dead glaciers. Reid’s use of 6 alpine ’ con¬ 
flicts with the well-established use already mentioned, and 
the terms 6 live ’ and 6 dead ’ are clearly misleading, as the 
great majority of the active glaciers of the world fail to 
reach the sea. I shall abbreviate 6 tide-water ’ to tidal and 
employ non-tidal as its antithesis. 
LYNN CANAL 
The order in which the glaciers were observed was from 
east to west, and it has been found convenient to adopt 
this as the order of description also. 
On the islands of southeastern Alaska there are no 
glaciers, and those of the mainland, south of Juneau, nestle 
in recesses of the mountains so far from the steamer route 
that we had only distant glimpses. But in Lynn Canal we 
followed a great fiord between ranges at once so lofty as 
to project well above the snow-line and so bold as to ex-

was used by Russell as early as 1892. See Am. Geol., vol. ix, p. 322, 1892.
