Your right, I was looking at the garden of the manor house today, there are some interesting bumps and lumps in the landscape there!
The stones in the river near the bridge are also worth another a look.
I have been building a 3D model of the landscape with Vista-pro and 3DSMax but it is slow going as I keep findng more to add!
oh for a Silicon graphix machine to render it up! ;0)
