Bonnington Linn is seen here from downstream to the north.1 The waterfall is depicted at the upper centre of the sketch as a row of tightly hatched vertical lines. Beneath the fall the River Clyde twists and turns through the gorge in the foreground. There are similar views on folios 8 and 8 verso (D26273, D26274). Turner made these on his way to Bonnington Linn from Corra Linn to the north. For further sketches of the Falls of Clyde see folio 1 verso (D26260).
