Abstract

During the past year a number of deep wells were sunk in Des Moines County. Some of them reached such extraordinary depths before touching rock, or without touching rock at all, as would clearly show the presence of buried river channels. In a paper presented before this society a year ago I stated that the pre-glacial and present drainage systems in this region were practically the same. From facts recently brought to light I must necessarily change that opinion. To what extent remains yet to be seen.
