Under the Cliffs, 1871 (from Sketchbook)

Black and white sketch of a tall, narrow passageway formed by cliffs with a boat on water in the bottom left corner. The cliffs are drawn with varying shades of gray, with darker shading near the top and lighter towards the bottom. The boat, on the left, appears to have a rounded front and a flat back with two long objects extending upwards. The water is depicted with short lines. Handwritten text at the bottom right reads "Under the Cliffs" and "June 10 '71".
