‘‘The most that can be reasonably claimed for ice-work is that 
it smoothed off the intervalley ridges and also the valley sides. 
The valleys are stream valleys, like valleys everywhere, and only 
slightly modified by ice action.” 
“Let us hope that assertions of the glacial origin or deepening 
of the Finger lake valleys (or any other valleys) will cease, and 
that former statements to that effect will be corrected. 
1906 — R. S. TARR. 
In discussing erosion in the Seneca valley, he says: “In this 
valley there is a general condition of remarkably perfect, broad, 
mature tributary valleys hanging several hundred feet above the 
lake level, at about the 900-foot contour. They are truncated by 
the straight, smooth, lower steepened slope of the main valley, so 
that they stand out prominently ,with open mouths, clearly discord- 
ant with the main valley, and about 1500 feet above the rock floor 
of the Seneca valley at Watkins. 
“When the hanging valleys of the Finger lake region were first 
recognized, and ice erosion proposed in explanation of them and of 
the main lake valleys, there were few who accepted the conclusion 
advanced; but now the great majority of American physiographers 
accept the ice erosion explanation for this region, as well as for 
others. 
1906 — W. M. DAVIS. 
In connection with a discussion of “The present condition of the 
problem of glacial erosion,” Davis states: “It has thus come 
to be believed by a number of observers that the glacial erosion 
of Piedmont lake basins must be extended to the over-deepening 
of the main mountain valleys far upstream from the lakes, and that 
the retrogressive glacial erosion of cirques carries with it the sap- 
ping and sharpening of the culminating ridges and peaks. The 
last named effect is truly not the direct work of ice, but it is so 
closely dependent upon glacial erosion that it should be included
