I was drilling a hole yesterday on the South Saskatchewan and hit a stone at about a foot. I grabbed a chisel and chipped it out. The thing was larger than a looney and 1/2" thick. The ice was about 28"
Hitting pea size gravel on the river with your auger is common and it sure wrecks the blades. My question: How is it gravel freezes in the ice? I was fishing in 12' of water.
