With the page turned horizontally, this drawing is part of a sequence working in from the back cover of the sketchbook, which correlates with accounts of a voyage Turner and others made from Plymouth south-east to Burgh Island, returning by land towards Plymouth. The sequence begins on folio 275 (D09476; Turner Bequest CXXXI 186a), under which the overall trip is discussed, and may extend as far as folio 228 verso (Tate D09382; Turner Bequest CXXXI 139a).
The sketches between folios 179 verso (D09462; Turner Bequest CXXXI 179a) and 261 verso (D09448; Turner Bequest CXXXI 172a) were made around the Great Mew Stone, south-east of Plymouth Sound, as discussed under D09462. Here the Mew Stone itself is not shown, but rather the view west to the far side of the entrance to Plymouth Sound, with Rame Head on the horizon to the left of the coast around Penlee Point.
A stain to the right matches that on folio 266 recto opposite (D09457; CXXXI 177).
