An Esker Group South of Dayton.

the withdrawal of the ice. This cut has been extensively used 

 by the Cincinnati Northern Electric, which runs alongside, in 

 securing ballast for its new roadway. 



No. 2. (Figs. 1, 3, 4.) This starts just within Calvary Ceme- 

 tery. A short longitudinal cut has been made on the west side 

 of this end, furnishing the gravel supply for the cemetery. 

 From an abrupt rise it proceeds southward, coming alongside of 

 No. 1, and following almost parallel. To the south it branches 

 and ends bluntly on the Miami Valley in two prominent knolls 

 ahgned with the cut of No. 1 (Figs. 1,6). Water is imponded 

 at several points between No. 1 and No. 2. This ridge is sep- 

 arated the greater part of its length from the kamy area to the 

 west by a distinct and deep trough.

 turn and steep rise shows in background. 



Kamy Area to the West of Eskers (Figs. 1, 5.) The kames here 

 show a tendency toward alignment in short ridges. Sometimes 

 they appear to radiate from a common center. Artificial cuts 

 facing the valley show prevailingly fine material indicating by 

 the stratification a very active play of waters. 



Studies. 



Proxiinitv of Eskers. The distance between the two eskers 

 is always slight. The surface outline of this distance is usually 

 similar to a parabola shaped trough of such a size that if one of 

 the adjoining ridges were inverted it would approximately fit 

 the trough. The drainage from the troughs is principally 

 through the soil. 



Height of Eskers. The variation in altitude of the crest-lines 

 and of the troughs gives var^'ing heights at different points. No. 

 2 by aneroid measurement varies from 35 — to 95+ feet in 

 height. No. 1, if measured, doubtless would give similar results.
