Medium: Pen and ink on paper
This dirty and worn plan is made from two pieces of paper conjoined. Place names are difficult to read. High Willhays (High Willhayse) and Yes Tor, two of Dartmoor's highest points, are badly obscured by the dense drawing style used to represent relief. A green wash indicates Dartmoor Forest. The remains of Oakhampton Castle are marked by a crosshatched mound. A red line passes through the drawing on the left edge. Two crosses may mark observation or triangulation points.
