HUGH MILLER GLACIER 37 



had progressed so far as to render its surface almost black 

 from the accumulation of residuary moraine stuff. These 

 relations are indicated in figure 17. The condition in 

 1894 was intermediate between those of 1892 and 1899. 

 A comparison of Reid's photographs and mine shows 

 also that the Charpentier had lost in thickness as well 

 as area, the lowering near its front being estimated at 

 about fifty feet. 



As mapped and described by Reid, Hugh Miller Glacier 

 rested at one point against an island, and only the portion 

 south of the island yielded bergs. The northern division 

 of the front descended to tide-water, but was covered at 

 its margin by debris and had no cliff. In 1899 the front 

 had retreated so as to open a narrow channel west of the 

 island and expose the top of another island on which a 

 tongue of the ice rested. South of this point the ice cliff 

 had retreated westward to an average distance of 1,000 

 feet, the maximum being nearly 2,000 feet. It still 

 yielded bergs, but sparingly, and was probably approach- 

 ing a non-tidal condition. A large nunatak at the south, 

 which was mapped and photographed by Reid, was more 

 fully exposed than before, and a small one had appeared 

 between it and the ice cliff. Near the northern end of 

 the cliff the distortion of dirt bands and an uprising of the 

 surface of the ice suggested that another rocky islet would 

 soon be exposed. The retreat of the northern portion of 

 the glacier face had laid bare a group of rocks projecting 

 slightly above the water, and a larger rock knoll was 

 gradually emerging. At one point it projected as a nun- 

 atak about 150 feet above water-level, and farther on was 

 revealed at the water's edge. The average width of the 

 space here abandoned by the ice is about 1,500 feet. 

 (See pi. HI.) The condition in 1894, as indicated by 

 photographs, was intermediate, but nearer to the condition 

 in 1899 than to that in 1892.
