Look at the average temperature for the 24 hour period.
...... notice how the gap is larger at the bottom of the crack. this means the ice is sinking as it cracks. it lifts you up and then drops you back down with water moving in the holes big time when it cracks open.same hole, just zoomed in.
good post 3300 but not sure what you are talking about hereOnly big cracks I've seen is on Maxy which is a large lake, small lakes I've never seen them so I'm not familiar with what you are talking about. Your from great lakes region so you probably seen allot of big cracks so can you explain more what you are talking about. Or post a link that goes indebt. I googled "dangers of cracks in frozen lakes" and didn't find anything.To me If the ice is sinking then water would be gushing out the hole other wise its not sinking. Or are you talking about what happens to the ice right before you fall thru the ice. Also when ice cracks to me that means its freezing and I always figured when doing that the crack freezes the water in the crack soon after it cracks bonding the crack together.
I do but I don't lol .... It's getting a little iffy for my liking to be out now . I'm just ready for these negative temps to go away !
If it wasnt going to be so gosh darn windy, id be planning on fishing saturday and sunday. Im not going to fight big wind on slick ice. Getting out on thursday, we will see what comes about after the weekend.
