Abstract The extensive loess deposits of southcentral and southeastern Idaho have been delineated and mapped. Depth of the loess over much of this area is between 50 to 100 cm thick. The thickest loess deposits are south and east of the Snake River where depths of loess up to 36 m have been measured. Thickest loess deposits are parallel and immediately adjacent to the Snake River. Loess source in the uplands in southeastern Idaho appears to be the Snake River Plain. No pattern of loess sorting was evident on the Snake River Plain; however, there was sorting in the uplands to the southeast of the plain and perpendicular to the Snake River.
