Intro to Shipwreck Diving 2019 With BSA & GLSPS Youth Groups "Photos"

Article in "Lake Superior Magazine"

BSA Venture Crew 820 divers met Great Lakes Shipwreck Preservation Society (GLSPS) members on-board the R/V Preservation on July 27th at the Silver Bay Marina to dive some of Minnesota’s shipwrecks.  Now entering the seventh year of collaboration, the Crew and GLSPS work to provide an amazing opportunity to the scouts, as well as create a legacy for future generations to preserve Lake Superior’s shipwrecks. Diving shipwrecks allows the scouts to touch a ship more than a century old and connect with history. It makes history real.

GLSPS Boat Captain Corey Daniels and Jimmy Christenson, along with a special guest passenger Konnie Le May, the Editor to Superior Magazine, joined the 4 BSA Scuba Venture Crew members aboard the ship. Le May will publish an article on the partnership between BSA Venture Scouts and GLSPS, highlighting GLSPS’s work to find and document lost Great Lakes shipwrecks. Of the 12 divers and non-divers on this trip, 7 are GLSPS members with 4 of them both members of GLSPS and BSA.

The R/V Preservation met up with other Venture Crew divers already moored to the shipwreck the Madeira, a 436-foot steel schooner-barge that sank on 28 November 1905 during a fierce November gale known as the Mataafa Storm. The ship crashed broadside into the solid rock cliffs known as Golden Rock Point. With a surface water temperature of 48 degrees which dropped to 38 degrees at the Madeira’s pilot house 80 feet down, the scouts appreciated R/V Preservation’s configuration that allowed them to conduct multiple dives throughout the day without swimming across the bay to the shipwreck. The chilly water temperatures did not dampen the scouts’ enthusiasm as they explored one side of the shipwreck, from bow to stern, with visibility of over 30 feet. After conducting the appropriate safety stops, the scouts surfaced and returned to the dive boat.                


After a 90-minute break on R/V Preservation, the northern Minnesota black flies chased the scouts back into the water for their second dive. The divers examined the Madeira’s bow section at a depth of 30 feet then swam around the point to cover the huge section of the shipwreck’s side wreckage that lies in water 30 feet deep. The cold water temperature resulted in a shorter 32 minute dive, but no less enjoyable.




The next day, the group split with seven scouts doing a shore dive off Stony Point near Duluth and the two closed-circuit divers returning to Silver Bay to meet with four GLSPS divers to film the Madeira at night for the 3D model that you see above. At Stony Point, the scouts dove lava flow formations looking for shipwreck parts from a tug that sank near shore 120 years ago. Despite the 39-degree water, the unique bottom contours and texture of the lake fascinated the scouts who spent 30-60 minutes in the calm shallows. They also enjoyed basking on the lava formations on shore after the dive, absorbing the sun’s heat. (Black basalt lava flow that is marked by gouges and ridges left behind by glaciers more than 12,000 years ago).


We want to thank GLSPS for hosting the outing for the divers, and for the boat captain (Eagle Scout) Corey Daniels and 1st mate Jimmy Christenson for taking us   out on the R/V Preservation. With the 9 divers, we had   2 Dive-Masters, 2 Instructors,   4 Advance Open Water divers, and 2 Advance Open Water students.
