Current frost depth Minnesota?

[MinnesotaEric]

Anyone happen to know what the current (march 3, 2016) frost situation is here in Minnesota around the Anoka area? I need to start pounding posts as soon as the frost is out of the ground. Driving the tractor the other day I was cutting in to the ground about 6 inches (sloppy, loose, muddy). Its been colder the last couple of days and I don't know what the frost might be like deeper in the ground as opposed to what I see at the surface here. Just thought I'd ask on the off-chance anyone here might happen to know the situation.

Here you go. Pick your area. If there is no current data, look at historical data or a different region in Minnesota.

We worked all winter placing fiber from Cologne MN into the Metro near the new stadium. Never seen frost more than 12 inches deep. Roads froze down to 30 inches in places. Odd year!!! We only shut down a few days due to Water freezing for drill rigs. After this weekend you should be ready to go. forecast is warm for a stretch.

Snow cover, exposure, and soil moisture all effect frost depth.

Around here the county road commission maintains a frost gauge for managing frost law enforcement , maybe yours does also.
