It was about ten years ago. My dive buddy (boat owner) and I were looking for a supposed wreck reminants about 3-5 miles out from the airport. We started east of the Price Wreck off the airport and slowly when east watching the depth sounder. After going out about (from what I recall 1 to 2 miles?) 25 minutes we saw a big blip on the sonar. But only one. We went farther. Another blip. We moved around that area for 15-20 minutes and finally stopped over one of the big depth increases – something on the bottom. We anchored, suited up, and dove. We never found any wreckage but we did come across some huge boulders, or what seemed like boulders, the size of a volkswagaon beetle. They were space fairly far about, maybe (?) 40-50 yards. I saw the only walleye school I ever managed to get on video (was filming the dive) and also found a nice brass knobbed ice fishing spud bar (lying up against one of the boulders in a little rock pile field). I never expected to find such big structure out there. Would love to go back and try to find the area. That’s the best I can tell you.
