Description
A bird’s eye view of a farmer riding his tractor along the fence line farming his hilly Loess Hills field.
Loess, pronounced "luss," is a German word for loose or crumbly.
The Loess Hills are a gritty, lightweight, porous material composed of tightly packed grains of quartz, feldspar, mica, and other minerals. Their extreme thickness of the loess layers (as much as 200 feet) and the intricately carved terrain of the Loess Hills make them a rare geologic feature. They are extremely fragile. Similar to a sand dune, the Loess Hills have the highest erosion rates in the U.S., almost 40 tons per acre per year. For that reason, Iowa farmers practice terracing and contour farming to limit erosion.
