Wonder if anyone has had to dig lately? I need to put some tile in this spring, and I think the frost line goes down pretty far here in MN. Anyone know if it is 4 feet deep??
County, pushing snowbanks back, seem to dig in dirt pretty easy. Good snow cover in ditchs, insulation. Otherwise. Hear from 20 - 28 in. As far as how soon the frost goes out..... depends on type of spring. Can go really fast or take for ever ( month)
