From the Apollo 15 Preliminary Science Report (NASA SP-289, 1972):

Station 6, the easternmost point sampled on the Apennine Front, is nearly 3 km east of St. George Crater and 5 km southeast of the LM. The site is on the north-facing slope of Hadley Delta, approximately 90 to 100 m above the mare surface. The surface slopes from approximately 5° to 15°. A subtle difference in soil characteristics at the sample site may be expressed in the fine granular appearance and deeper burial of fragments toward the east as compared with coarser textures (higher concentrations of centimeter-size fragments) and less burial west and north of the Rover. Fragments greater than 10 cm across are uniformly but sparsely distributed in the intercrater areas, with notably higher density around a 12-m-diameter crater. The only fresh craters present are less than 1 m in diameter, and from these only clods of soil or soil breccias were excavated. Some samples were collected from the 12-m-diameter crater north of the Rover; they are considered to be recycled from underlying regolith. Other samples are not associated with this crater. Hence, two types of environments from which samples were taken are defined at station 6-the 12-m-diameter crater environment and the Hadley Delta slope environment.
The rim of the 12-m-diameter crater is subdued but distinctly raised approximately 0.5 m above the surrounding slope. Several 1-m-diameter sharp craters are on the rim of the crater. Parts of the rim have well-developed benches, particularly the north and northeast sides, and a bench is observed on the inner wall on the northeast side of the crater. Small parallel east-trending lineaments are visible on the north wall of the inner bench near the sample site. The slope in the immediate vicinity is 15° to 20° toward the crater floor, but the regional slope is approximately 10° N. Filleting and burial of the rock fragments are less than might be expected for undisturbed ejecta from the surface by the small, fresh, 1-m-diameter craters. Dust cover on many of the rock fragments seems higher than normal, probably the result of ejecta from craters in the immediate area. The north rim of the 12-m-diameter crater has a higher-than-average albedo, and light-colored soil was kicked up during sampling activities.
Lineaments occur locally in the Hadley Delta slope environment. The soil is finely granular with centimeter-size fragments comprising 1 to 15 percent of the surface layer. Larger fragments are sparse and are not directly associated with specific craters larger than a meter.
