Ar. I'll be back. Alt route: follow Brightholmlee path up to wood edge. There's a stream there. Follow down a few yards and then cross to E side of it, then just keep parallel to it till you hit the scarp edge and rampart. Damaged tree should be visible to your right. Careful when there.. huge severed bough above, not sure how it hasn't dropped. Could land on stone as well when it does. Place needs a saw party.
