The discoveries of localities showing glacial scoring in southeastern Iowa have been somewhat numerous during the last few years. In a paper presented before this body a year ago I called attention in detail to the different known exposures of glaciated rock in this region, and pointed out that the testimony they gave was unanimous as to the southeastern movement of the ice sheet. Since then another exposure has been located that seems to bring conflicting testimony.
