This past weekend I went up to Lake Winnipeg in Canada (very near the famous Lockport known for giant channel cats) We were targeting walleyes through the ice. The fishing was good. We caught lots of really nice walleyes but it was the thickness of the ice that was most impressive. 52" of ice. The picture tells the story. I'm 5'7" and we were right to the powerhead on the auger when we hit water.
