Entrance to Skookum Flats, a few miles West of Crystal Mountain.
This is the Greenwater area, home to tons of free camping and mountain bike trails.
A few pics from 2009 when I was camped up there, did not get anymore on the trail, battery depleted.
Not my video, but this gives you a idea of what the trail is like.
Many of our trails are like this, under thick tree canopy.
I have ridden this trail many times since the early 90s.
