Abstract

Glaciated bedrock surfaces are of course known from many parts of the world. Many have been described. Some have been examined in detail for what they might disclose as to the behavior of glacial ice and the process of glacial erosion. Many undoubtedly are or have been exposed in Iowa and other parts of the Midwest within recent times, but few have been reported in the literature, at least from Iowa. Only ten localities having striae are shown, in Iowa, on the Glacial map of North America (Flint, 1945), whereas there are relatively many more shown in states to the east. Most of those for Iowa are in the southeastern part of the state (Fig. 1), quite distant from the occurrences to be described in this paper. Those shown on the glacial map are from various sources, possibly brought together in a paper by Norton (1911), although a few reported by Norton do not appear.
