Spring cascade by the parkway.
Just before Tanbark Tunnel.
Looking down as the cascade approaches the parkway, you can see the culvert which it disappears into (look to the right).
The opposite side of the parkway has trails, but no creek.
Maybe 40 feet below the level of the road, you can hear the water, and barely see it through the laurels. And this is with winter's lack of foliage on the trees.
