The long since frozen sheet that made it through the rain storm weeks ago is about 8-12 inches thick
Last thursday sheet is 6.25 inches thick and freezing super slow with the insulating snow.
Last fridays sheet i havn't gone on my guess is 4 inches but no guarantees.
And the death trap sheet that barely froze the day before or of the snow and wont hold a coyote. This comprises only a few small holes but super dangerous.
As usual the ice isn't uniform and constant checking is reccomended.
