CREEP IN CASS COUNTY, N.D.

An asphalt walkway has been built above a slope (small, wooded valley; left edge of photo) undergoing creep. Soil flow under the walkway is occurring at differential velocities (the left edge faster than the right), causing the thin asphalt layer to stretch and break. Note that the resultant cracks run parallel to the slope. The fenceline to the right of the walkway is new, and (as of the time of this photo) has not yet been affected by creep.

This photo was taken at Fargo's Trollwood Park.
