This is obviously off-topic, but I'd like to utilize the breadth of Alberta diving experience on this thread right now.
About two years ago my dive buddy and I found a weight belt (no diver in it) with a plastic buckle and about 40 lbs of lead fastened shut at about 50 feet in Cameron Bay in Waterton Park, Alberta. This was a surprising amount of weight, and it was also surprising that the buckle was closed and no one was in it.
Can anyone shed some insight into the history of this item? Were there any incidents at Cameron Bay in the past several years?
Absolutely no knowledge of that area, but a boat I was on had several weight belts that were spare weights, normally fastened around a seat support, but one was not and we lost it on acceleration.
