The region specially discussed in this paper is about five square miles in the northwest corner of Fremont County, Iowa, which is the southwest county of that State. It lies mostly on the bottom lands of the Missouri River. It is bounded on the east by a tableland rising abruptly in steep bluffs cut by deep ravines. These bluffs rise 250 to 300 feet above the plain and are composed mainly of yellowish loam, typical loess. This yields easily to erosion especially when water soaked. At such times, its cementing lime, which when dry holds it firm like a soft rock is dissolved and the mass washes or creeps like wet sand.
