Since the. pioneer studies of Russell, Reid, and Muir among the 
glaciers of southern Alaska, the extension of exploration has gradu- 
ally brought more and more of them within the range of observation, 
until now most of the more important have been located and a few 
of them carefully described. The ice-fields of the St. Elas region 
are among the most interesting of these, and, thanks to the researches 
of Russell, Gilbert, Tarr, and Martin, are among the best known. 
It was my privilege in 1906 to explore portions of the coast immedi- 
ately east of the field studied by these men. ‘The present paper is 
presented in order to record for the first time? the glacial features of 
that strip, and to form the basis for the further exploration and com- 
parative study which is sure to come in later years. 
From Yakutat Bay to the Alsek River the outer coastal mountains, 
for which I propose the name Brabazon Range,’ is separated from the

The accompanying map has been redrawn and adapted from the field map 
prepared in 1906 by my associate in the field, Mr. A. G. Maddren. Certain addi- 
tions are based on photographs and surveys by Mr. A. J. Brabazon, of the Canadian 
Boundary Survey. 
2 Previous maps show the position of the larger glaciers, but no description of 
them has been given.

the first topographic map of these mountains. The range begins at the lowest
