David Wallace-Hadrill and Janet Carolan have identified this sketch as a view of Loch Awe from near Dalmally at the head of the loch. There is a single arched bridge in the foreground and what the authors see as a set of small buildings, perhaps including a water-mill at the right.1 Turner seems to have made only two sketches of Loch Awe in 1831. The other is on the other side of this sketchbook page; folio 85 (D26908; CCLXXIII 85).
