Bill Stone drives the 3D DWM (digital wall mapper) back to the surface at Wakulla basin following the June 19th data collection run to Grand Junction (A-B-C tunnels). A distinctive feature of the DWM, even from a distance, is the forward canards. These servo-controlled diving planes allow for finger-tip control of pitch and roll by the operator and dramatically improve maneuverability. [photo ©1998 Paul Heinerth].
