We, like a number of the other replies have similar arrangements for SAR. In our area, the sheriffs department generally takes the led for a lost person search. However, both state and federal park officials generally are the responsible agency, if the lost person search takes place on park properties. We have available, two volunteer dog teams for searches. Our team generally does not take an active role in the search phase, but is responsible for the actual rescue, whether it is a technical, overland, water or other terrain. We have similar equipment that others have listed. We also work with Maryland State Police and the U.S. Park Police helicopters, with their associated equipment. Pete
