Caption: Sediment in the street of Des Moines, Iowa, after rains. This occurred because measures were not taken to protect the soil from erosion during development.

Caption: A solifluction lobe in Alaska. Solifluction is the slow downslope movement of waterlogged soil. A solifluction lobe is an isolated, tongue-shaped feature, formed by more rapid solifluction on certain sections of a slope showing

variations in gradient. It commonly has a steep front and a relatively smooth upper surface

Photo 4Caption: Salt marsh mud exposed on the

beach face is a sure sign of island migration. Here at Capers Island, South Carolina, storm waves have pushed the sand from the beach back into the salt

marsh, exposing the underlying salt marsh mud. In addition, the overwashed sand is starting to impede the flow of water in the

gut.

indicates a rather calm day. Photo by Carole Y. Swinehart.

Caption: The Paiute Point Sanddune is climbing out of the valley of the Little Colorado River and over the Adeii Eechii Cliffs near Cameron, Arizona. The progress of the two echo dunes on the left

is halted by reverse wind eddies from the obstructions.

Caption: These sand seas consist of large areas of wind-blown sand. In Saudi

Arabia the most famous of these is the Ar Rub al Khali, the Empty Quarter.

Caption: Rain saturated soil and gravity created this landslide and debris flow near Seward, Alaska. Grading and steepening the roadcut during the construction of the road may have

affected slope stability.

Caption: This landslide resulted from oversaturation of soil in California. The failure occured

as a massive slab broke free from the wall and slid downward.

Caption: The muddy waters of the Chang Jiang (Yangtze River) in China shows it carrying a heavy sediment load coming from surrounding eroded lands. Photograph was included in Soils, Society,

and the Environment, 2005.

Caption: Solifluction lobes. Solifluction is the slow downslope movement of waterlogged soil. The rate is around .5 to 5 centimeters per year. This especially occurs in regions underlain by frozen ground, which

acts as a barrier to water percolation. Solifluction is generally more rapid than soil creep.
