Agricultural activities are responsible for extensive disturbance and destruction of archeological sites throughout the region and beyond. Plowing moves the artifacts from their original locations thus making it difficult to tie them back to the contexts in which they belong. It has become a relatively common practice for many archeologists when faced with this problem is to simply blade off the disturbed area of the site, usually the upper 30 to 40 centimeters, so that they can better access undisturbed areas. They do this because they believe that since the artifacts have been moved out of context that they are …

Rapidan Dam and Reservoir are located along the Blue Earth River south of Mankato, Minnesota. The dam was constructed in 1911 as a source of hydroelectric power to supplement the surroundings communities. Currently, the reservoir is heavily silted and provides little hydroelectric benefit while proving costly to maintain. This study (1) defines the sedimentary, geomorphic, stream flow and suspended load characteristics of the reservoir for 2008-2009 and (2) compares these parameters with those available from 1985 (23 years prior). Stream gauging and sediment sampling took place in 2008 and 2009 at three monitoring locations (two upstream and one downstream of …
