Grabau's interpretation of late Tertiary drainage in the eastern Great Lakes region, the intention being to show the general kind of drainage rather than the exact location of the streams. The "Rome" River with source at Little Falls is well shown. The three south-flowing streams should, in the opinion of Dr. Miller, be represented as north-flowing, at least immediately prior to the great ice age.
