Grindon Monday July 21/1913
Rained all afternoon but we are out anyway.
Krich after collecting in the Millus quarry
concluded that the horizon is near Fern
Glen and Burlington. Before he had seen the
locality he was of the impression that the hori-
gon is in the Tennesseeo. However he now
concludes mainly on the basis of the Bryozoan
that the time is either upper Kinderhook
or early Burlington.
Professor Krich said the facies of the
Grindon is German Permian. This is true
for the dolomites here duplicate the
Grindon while in both places there are red
shales and gypsum deposits.
