The term paha was first applied to isolated knobs and ridges within what we now know as the Iowan drift border by McGee, who refers to them as "loess-capped eminences, sometimes elongated to ridges miles in length, sometimes shortened to elliptical hills," and again describes the individual paha as an "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 loess plateaus."
