The loess capped ridges associated with the Iowan glacial drift plain in northeast Iowa have been called "paha" by McGee (2)*, a term used by the Dakota Indians to describe these peculiar geological formations. The paha have been described (2) as "the elongated swell of soft and graceful contour, standing apart on the plain, or else connected with its fellows sometimes in long lines, again in congeries, and locally merging to form broad plateaus." The occurrence of paha in the Iowan drift plain of northeast Iowa has been reported by several authors (1, 2, 4, 5, 6, 7, 9). Most of the paha were said to occur in and around the periphery of the Iowan drift border adjacent to the loess covered Kansan drift (4).
