Index of Subjects --001a11c12240583ae904f9d9c87e Content-Type: text/plain; charset=UTF-8 Thanks Fred, but in a dune system, wouldn't that mean that the slacks would be less than half full with water? These are sand dunes...very porous, so I'm suspecting water leaching in from the hills of the dunes into the slacks just couldn't fill them. This is unlike the condition in vernal pools where there can be ample elevation around from which water could leach in to the pool area. I'm thinking there has to be a significant rain or snow fall to fill them. Randy _________________________________ RF Lauff Way in the boonies of Antigonish County, NS.
