Ever wonder what is responsible for those volcano looking mounds of dirt out in the ditch?

It is a Crayfish! These “chimneys” are used to burrow down to the water table where they make their homes for much of the year. Impact7G looks for these features during wetland delineation work as they are an indicator of wetland hydrology. This crayfish was in his defense posture when we snapped this picture in the field.
