Ravensworth, stream bed and sandstone arch outlet

A natural dell runs through the north and east edges of the Greenhouse Walks woodland. The stream at its base is now dry. An outlet for the stream is covered by a sandstone arch, which is visible at the south-east of the woodland. The present line of the stream differs from the 1785 plan. It has been developed into part of the ornamental garden by the additional of a gravel bed and rock edging.
