Ice safety info

[jcrayford]

I've been looking here on AO. Saw a chart last year/year before that on ice thickness for walking/atv/vehicles, but can't seem to locate it. I'm hoping someone has it and could post it again please?

I'm wondering what everyone feels is the SAFE working ice thickness for a 1000 pound ATV (ATV itself weighs 1000#). I seem to recall from said chart that 4" of ice was good for a single person walking, but can't remember the rest of the chart.

Just thinking ahead for the hard water season.

Thanks in advance.
