We have cut nearly everything at least once.  Today we weave through a virgin stand of hemlock trees.  Awesome.  It is cool and dark under the thick canopy and the needle strewn ground is soft underfoot.  The narrow humid creek valley makes for just the right conditions and it is literally filled with hemock ranging from tiny saplings to towering trees with as much as 5 foot diameter trunks.  The rugged terrain surely played at part in saving them from the axe.   I hope they are here for many more years to come.
