Lake Minnewaska. 29 
South of Paltz point the eastern front of the mountain pre- 
sents a nearly unbroken line of high cliffs for many miles along 
or near the crest of the anticline. The nature of a portion of 
this escarpment is shown in plate 3 
Two miles south of lake Mohonk there is a shght depression 
in the crest line through which the road to lake Minnewaska 
passes, and there are several other depressions of less amount. 
Millbrook mountain is the culminating feature of this portion 
of the range, beyond which its front is somewhat more irregular 
in contour. 
Lake Minnewaska is similar to lake Mohonk in appearance, 
but it is somewhat larger. It was not ascertained whether its 
basin extends into the Hudson shales, for there is a continuous 
rim of grit surrounding it. As a very great thickness of grit is 
exposed above the water level in this vicinity, it seems probable 
that the bottom of the lake is in or very near the shales. ‘This 
probability is increased somewhat by the presence of the steep

cliffs and the width of the valley or cleft in which the lake lies. 
In figure 2 there are shown the principal structural features at 
this locality. 
The cliffs which extend along the eastern side of the lake are 
very high and precipitous. As at lake Mohonk, the rocks are 
greatly fissured and are. traversed by many deep wide clefts. 
The dips are gently anticlinal about the Jake, which is on the 
axis of the flexure. but they increase in amount to the east and 
west. The lake empties to the southward through a wide gap, 
into the synclinal valley of the Coxingkill, and it may be re- 
garded as the headwaters of this stream. 
_ A miie northeast of the lake the anticlinal on which the lake 
is situated is crossed by the road to Port Hixon, and in the
