Jay Hanson from North Shore Scenic Cruises has helped the GLSPS on many projects. Jay has many years of experience as a Captain, dive shop owner, dive instructor and commercial diver.

Jay has taken a different path for the past few years and his scuba charters are no longer available. However, in 2012, Jay purchased the Wenonah which was previously used to transport people from Grand Portage, MN to Isle Royale, MI. He now offers day cruises on the North Shore of Lake Superior and is docked at the Silver Bay, MN Marina.

If you are interested in booking a 2 hour - day charter cruise on the North Shore of Lake Superior, please click on the logo above for information on joining him and his staff on a north shore day cruise.

Underwater Pumpkin Carving


Square Lake  a
t Golden Acres 
15150 Square Lake Trail Stillwater MN 55082 (South side of Square lake).                                                                                                          

No tricks!  Diving’s a treat!  As a warm-up for Halloween and fall, BSA Venture Scuba Crew 820 invites certified divers from around the Twin Cities to join them carving pumpkins at Square Lake near Stillwater, on an underwater dive training platform, 22 feet down. 

“Bring your own pumpkins”


If you need equipment there is a $30 cost for the outing: includes 1 tank of air, wet-suit, hood,    gloves, BC, regulator, carving tools, and FUN.  (If we do not have a wet suit that fits you, you will have to rent one on your own)  (Golden Acres vehicle and per-person fees are not included)


The water temperatures should be in the 60-degree range, with the best water visibility of the season!  The pumpkins will spill their guts out on shore prior to the dive and then add some Scout-rendered underwater “vegetable surgery”.  Last year it took a mere 32 minutes of underwater precision carving to turn ordinary garden gourds in to underwater masterpieces!     


To register, we need your name, age, phone number, height, weight, and shoe size.           

Sign-up cutoff date is Wednesday, October 3rd.
