This is figure 3-19 of the Apollo 15 Preliminary Science Report (NASA SP-289, 1972), which has the following caption (slightly edited):
On the side of Hadley Delta at station 6A, the Commander (David Scott) took a series of photographs with the 500-mm telephoto lens. The large crater in the foreground, at a distance of approximately 2 km, is Dune; and the series of white dots to the left of the LM (approximately 5 km distant) is the deployed ALSEP. The huge crater that forms the background above the LM is Pluton at a distance of 8 km. Pluton is approximately 800 m in diameter, and the largest boulder in the crater is approximately 20 m in diameter.
