Niagara Falls, Aug 8 - 1911.
At the Whirlpool Rapids in the Lower
Medina may be seen good examples of
bottom scouring and rolling up of the bottom
muds by the storm waves. Extend far to left.
Red Shales
30" sandstone 6" 30"
a. Some of the rolls show that the clay was
still soft and squeezed into the rolls before final
entombing. They are folded thus
8" thick by 14" long.
Basal sandstone. To the east of the
Whirlpool Rapids station about 2 miles may
be seen the contact of the white basal sand-
stone upon the brick-red shales of the Queno-
town. The contact is abrupt here, as a
rule the horizontal contact is very smooth
but in one place saw a decided channel
cut by the sandstone into the red clay.
