safe ice

[lesterl]

Can 4 inches of ice be unsafe if it looks good but you just had 3 days of thawing weather?

[Skeets]

Yes, it can be unsafe.

Wait for more below zero or colder weather.

It is real diffucult swimming below ice.

I would be a bit leery of 4" after it has been warm for a while. You could drill a test hole and check to see how much clear ice you have. If it is NOT real clear, I would stay off.

Unsafe unless you know the area and you see a hundred size 14 bootprints in the snow. I work on lake Independance in Hennepin County and have seen the spring areas thaw through the ice during a warm spell- I would not go there on foot, sled or atv I would stick to well traveled areas.
