I had the opportunity to explore some isolated alvars on Sunday. They were offside from cattle and snowmobiles and might be representative of wilderness recovery some 5 decades or so after the last serious attempts of humans to eke out a living from this land.
A burr oak:
Lichen on overturned stumps - how old?
There were tracks in the snow as well:
Any help in identifying any of them? Start with the moose and the snowshoe tracks and proceed from there.
