Scott took this photograph of the lip (covered with boulders) of Hadley Canyon between the slope of Mount Hadley Delta to the left and the east (near) wall of Hadley Canyon to the right with the 500mm telephoto lens.

165:30:14 Irwin: You know, looking to the south, along the rim, along this side of the rille. Dave, did you comment on that horizontal bedding that’s probably, oh, at least 1 kilometer south us? And higher, higher elevation.
165:30:32 Scott: On the other side?
165:30:33 Irwin: No, this side. [...]
165:34:44 Irwin: See what I was talking about down there, Dave?
165:34:45 Scott: No. What do you see?
165:34:47 Irwin: I see horizontal bedding.
165:34:49 Scott: Oh, yeah! I see what you’re saying. Some...Somewhat...Looks like it might be dipping very slightly to the east.
165:34:57 Irwin: Yeah. Right. You can see the exposed upper surface of that layer.
165:35:02 Scott: Yep. You’re right. (Pause) Yeah, I agree. Got it. (the picture)

Scott took the photograph with the 500mm lens.

“Bombarded by meteorites for billions of years, the Moon’s surface is pockmarked by craters ranging in size from microscopic pits to giant basins hundreds of miles across” (Light, plate 128).

David Scott is prospecting for lunar samples in a field of boulders on the edge of Hadley Canyon. He is picking up the hammer, with checklists visible on both arms. The one on his left wrist covers the drilling tasks that have occupied him on all three EVAs. He has a sample bag in his left hand. Scott is reflected in his gold-plated visor.

A buried boulder is visible next to the gnomon. Footprints are in the foreground.

165:51:31 Scott: Oooh! Oooh! You can see a boulder exposed to the surface here, which has got layering within it. It’s been weathered away, apparently, and just the surface top is exposed; but the boulder must be, oh, about a meter long with 2- to 3-inch layers in it.
165:51:58 Scott: Would you get a picture of that where I stopped, Jim, just a quickie cross-Sun? See where that thing (a buried boulder) is exposed there?
165:52:03 Irwin: Oh, yeah.
165:52:04 Scott: See those little layers.
165:52:05 Irwin: Beautiful.
165:52:07 Scott: Okay. I think a cross-Sun stereo would be neat right there.
165:52:10 Irwin: Okay.
165:52:11 Scott: Here. As a matter of fact, I’ll drop the gnomon; that’ll tell them what it was.
165:52:17 Scott: Just to get a real quick picture.

The TV picture shows Irwin as he rakes up fragment samples and pours them into Scott’s collection bag with Hadley Canyon in the background.

“Station 9A was both productive and fun. Scott and Irwin had clear objectives for the site and, because of the value of the station, were given extra time so that they could work without undue haste. They didn’t have any appreciable slopes to content with, so the work wasn’t physically demanding. And, finally, the site offered enough interesting detail that they were able to put their geology training to very good use. It was a fitting climax to the mission and indeed, as they prepared to drive off, Scott neatly summed up his pleasure and his buoyant mood. ‘Man, am I going to miss one-sixth g. This is neat.’”(from the ALSJ mission summary).

Raking the soil near the Rover for a collection of small rocks, the astronauts created an abstract “drawing” on the lunar surface, captured on film by David Scott. Irwin’s shadow is at the upper left of the picture.

Jim Irwin was standing beside Hadley Canyon on the north rim of the 45-m “Rim Crater” in the
right foreground when he captured this wonderful panorama of station 10.

“Although samples were collected, this station was primarily a stop for photography. The site was about 200m north-northwest of Station 9A. This offset distance provided a base for obtaining stereoscopic 500-mm and panoramic photography” (https://www.lpi.usra.edu/lunar/missions/apollo/apollo_15/surface_opp/).

The first photograph shows the lunar surface before Irwin put the core tube in position.
He then pushed it in by hand before hammering it in the rest of the way (second photograph). Core samples of the lunar soil were an invaluable method for deciphering its history.

“It’s hard to whack on the moon. Because the hammer only weighs one sixth. It’s got the mass, but you can’t get the force behind it,” said David Scott (Chaikin, Voices, p.80).

166:01:52 Irwin: I’ll grab the core while you take the pictures. [...]
166:03:41 Irwin: I’ll push a little more.
166:03:42 Scott: Yeah. Got a half a tube.
166:03:46 Scott: Oooh! Good. Nice. You got three quarters.
166:03:46 Irwin: Yeah. It feels like it’s hung up on a rock.
166:03:48 Scott: Okay. I got the picture.
166:03:49 Scott: Go ahead and hammer. Rock, huh? Oh, it’s going in. You’re getting it.
