That's nothing. I'm not averse to walking on lakes in the right conditions, but one of my frequent haunts in the swan hills has a kidney shaped little lake (unnamed) that we call "ghost lake" - because of the sounds it makes. Due to the shape it always gets a large crack and pressure ridge (by late november you can typically walk right up to it) but as the sun gets on it during the day and the ice expands and then in the afternoon as it cools down and contracts the lake emits these ghostly loud basso profundo hoots as the ice moves against each other under pressure. Standing on it (anywhere on the lake) at that time is amazing. it's like standing on the world's spookiest and biggest subwoofer making low owl noises... But definately enough to freak you the heck out the first time it happens and you have no idea why what you're standing on just did that... all around you <img src="/forums/images/graemlins/smile.gif" alt="" />
