This plan of the Menai Strait extends along the coastline of Conway Bay from Penmaenmawr to Conway. Triangles are ruled in ink and pencil across the map, allowing the location of individual topographical features to be plotted. Colour washes depicting relief are combined with numerical annotations ('spot heights') indicating the heights of the hills. The brown ink used for place names and heights has smudged, making legibility poor overall. An area calculation table survives in black ink in the top left margin, below the formal title.
