Here Turner records a rocky coastline and semi-circular cove shaped by a small headland extending out into the sea. Finberg asserts that this scene encompasses a coastal scene recorded near Folkestone in Kent.1 Presumably his identification of the landscape seems confident in light of preceding pages from folio 20 verso, many of which deal with the cliffs at Folkestone and towards Dover (folios 20 verso–21 verso, 22 verso–23 verso, and 24 verso; D17240–D17242, D17244–D17246, D17248).
The view is similar to a sketch from later in the sketchbook on folio 52 verso (D17293), the topographical sweep of the coastline and landmarks bearing resemblances. In the catalogue entry for the colour study Cliffs on the Coast, Possibly near Folkestone or in Cornwall of about 1830–5 (Tate D25185; Turner Bequest CCLXIII 63), Matthew Imms underlines the link between this later drawing in the present sketchbook and the tentatively identified cliffs in the colour study. Imms also draws attention to a possible parallel in the Ideas of Folkestone sketchbook of 1845 (Tate D35374; Turner Bequest CCCLVI 14).
