This is a continuation of the subject on folio 44 verso (D02999). The inscription presumably refers to Ben Cruachan, the mountain that rears up above the north eastern end of Loch Awe, and which Turner included in the title of his watercolour Kilchern Castle, with the Cruchan Ben Mountains, Scotland: Noon, shown at the Royal Academy in 1802. Although this has traditionally been identified with the watercolour of Loch Awe with a rainbow in Plymouth City Art Gallery and Museum,1 the present author has proposed that the work in question is a lost watercolour2 engraved by William Miller in 1847 (Tate impression: T05813).3
This sketchbook includes a long sequence of drawings of Loch Awe, many including the castle, of which that on folios 59 verso–60 recto (D03025–D03026; Turner Bequest LVI 57a–58) seems to have supplied the principal features of the view in the watercolour.
There is a 10 mm tear at the centre of the outer edge.
