The folks at Mt. Vernon are continuously unearthing artifacts from George and Martha Washington’s era to recent time. Archaeologists are continually working on the property to "unearth" the past. One of the steps they use is screening the dirt through a fine mesh screen to catch all the artifacts.

Dry Screening for other forms of mining and propecting is made easier with more automated equipment. Some of our topsoil screeners are being used in gold mining operations in Siberia!
