the last time I was there I drilled a hole and there was about 5 feet of air between the water and ice. Two snowmobiles were there about 20 minutes later as I was packing the truck. They didn't believe me and the two actually walked out to where the hole was so they could witness it themselves.
I have heard about this on & off for years now. I have heard stories of HHR surface ice being suspended as much as 30'. I can't even picture that! Do you by chance have any pictures of this? Seems with as many smartphones as there are out there someone should have some crazy pics of this phenomenon.
