Fisher. — River Terraces. 
PLATE 5. 
Various left-hand swings of the West River since the ice age. 
Fig. 5 shows two deeply compressed meanders enforced by the rock bar¬ 
riers on the down-stream side of each bend. River was suddenly 
withdrawn from the larger bend by cut-off or short-cut, leaving a 
very definite river channel. 
Fig. 6. Same rock controls prevented the river at the 225-foot level from 
eroding further to the left.
