ALASKA GLACIERS 



The front of Johns Hopkins Glacier has suffered less 

 change since Reid mapped it, but there has been some 

 retreat. A comparison of photographs made in 1892 and 

 1899 shows that more rock is exposed at the south; and 

 a remnant of ice I could see clinging to the mountain side 

 at the north showed that the front had within a very few 

 years held a position several hundred yards more advanced 

 than in 1899. Its determined changes were so small that 

 no attempt has been made to express them in the accom- 

 panying diagram. 



The remaining glacier of the three was indicated in a 

 general way on Reid's map of 1892, but its lower end was 

 represented by a dotted line, implying doubt as to its pre- 

 cise position, and no name was attached. It was more con- 

 fidently delineated by the Boundary Commission in 1894. 

 As my map and photographs give such determination of 

 the position of its ice cliff that future changes can be meas- 

 ured, it seemed proper to supply Reid's omission in re- 



spect to name. 



and the Harriman Expedition adopted 



the name Reid. I 

 am glad to be able to 

 illustrate somewhat 

 fully a feature bear- 

 ing a name so de- 

 serving of honor in 

 Alaska glaciology. 

 As already men- 

 tioned, the Reid Gla- 

 cier was a branch of 

 the Grand Pacific in 

 1879, but not many 

 years could have 

 elapsed before the recession of the latter made it indepen- 

 dent, and it is probable that its end then projected some- 

 what beyond the general line of the south wall of the
