portion of it was deflected to the north through 

 Glacier Gorge. Emerging from this gorge and 

 enlarged by the ice-streams from Mt. Otis, Mt. 

 Hallett, and other peaks in the Continental 

 Divide, it flowed on to thrust against the east- 

 ern base of Flat-Top Mountain. This bent it 

 to the east, and from this turning-point it began 

 to unload its debris on Bierstadt Moraine. A 

 part of its debris was dropped in a smaller par- 

 allel moraine on the opposite side of Glacier 

 Creek, and finally a terminal moraine was piled 

 against the western front of Green Mountain, 

 where it almost united with the terminal part 

 of the Moraine on the south side of Moraine 

 Park. 



The glaciers have formed and distributed 

 much of the soil of this region. Above timber- 

 line there are wide, sedgy meadows and tundras 

 and dry, grassy moorlands. Everywhere on the 

 heights where there is soil there is a growth 

 of Arctic-Alpine vegetation. Above the limits 

 of tree-growth are enormous ragged areas and 

 tiny ledge gardens that are crowded with a vari- 

 ety of brilliantly colored wild blossoms.
