We tapped 25 trees back on the 30th of January which was when it last thawed.
Our property is in the bottoms on a steep north facing slope. To date we have collected only about 7 gallons of sap. Don't know if the trees are still frozen solid, or if my tap holes have run dry. We'll try tapping another tree today to see if it runs any better than the others.
I'm hoping they are only frozen and not dried up.
