I love stories like this
Growing up in northern Ontario my dad used to read us poetry, with a family favourite being The Cremation of Sam McGee by Robert Service.
In 2009 they found the wreck of the A J Goddard on Lake Laberge (also using a fish finder) which sank just a three years before the poem was written. At the time my brother and I were excited thinking it was the same boat as in the poem, but later I learned the poem is based on an cremation in the engine of a different wrecked ship. It was very fun speculating though! You never really think of how dangerous those boats were.
Another interesting bit of trivia is that Parks Canada actually owns (manages?) two shipwrecks in the Arctic, the HMS Terror and the Erebus, which were only discovered in 2016 and 2014 respectively. Inuit oral stories and legends actually resulted in the discovery of the wrecks 170 years later, it's a very interesting story.
