They learned basic sketching, triangulation, offset measurements, and basic ship architecture.

  Archaeology & Documentation Class
S.P. ELY  Two Harbors, MN
August 24 & 25, 2002 

Dave Cooper instructs GLSPS divers in the fine points of documenting areas of ships. Several reference books were on hand to show examples of ship construction.

Pictured standing (left to right) are Ken Knutson, Jay Cole (Videographer), Byron Meyer, Randy Beebe and Dave. Bob Nelson and Bob Olson are seated at the table.

Dave also showed triangulation method on the ground using measuring tapes. 

Steve Daniel shared techniques for drawing features of a ship underwater. Complex forms of ship construction are broken down into combinations of simple shapes and lines. The underwater drawings made with pencil on matte polyester sheets are later transferred to paper on the surface and refined. 

Instruction took place in the park near the Two Harbors Lighthouse. Some artifacts from the ELY, including the bell, could be viewed in the light house museum shipwreck display.
