The Iowan is yellow, jointed
coarse, shading up into soil.
A few boulders appear in it
some pebbles & occasional little
bits (pockets) of sand.
The line between drift &
Buchanan is very sharp.
The Buchanan is here much like very upper weathered,
Aftonian , ^ [[insertion]] rather [[/insertion]] faintly stratified,
with a few rotten boulders, some
small boulders, - & pebbles & sand.
There are iron hollow concretions 
(looking like pebbles), also a 
little lime.
Took sample of drift & gravel.
There must be 15-20 ft of gravel.
The drift at bottom is typical
Kansan, with large boulders
(Says Prof. Calvin).
Some of the big boulders dropped
down from Iowan.
