Wind Erosion Vulnerability and Rainfall Mapping in the Southwestern United States

Northern Arizona Slides


Overview of an area looking southeast toward the western edge of an unnamed wash; note dune material on edge of wash in the photo background which shows up as yellow in the satellite eolian image. In the foreground of the photo is a lag gravel surface underlain by a sandy loam material containing some clay (this shows up as bluish-grey in the satellite eolian image).

Surface materials taken on lag gravels adjacent to human figure in the photo above. Note lag gravels forming the first centimeter of the surface. A combined sample of the lag gravels and the sandy loam below showed 55% by weight particles of less than 500 microns, but the lag gravels protect the surface from wind erosion -- this is bluish-grey in the satellite eolian image.
