Many boulder trails are found on the lunar crater walls and basin massifs. Some of the trails are smooth and nearly straight while others are curvy or gouge into the surface. In many cases by following a boulder's trail you are led back to its point of origin, useful information for a future geologist sampling otherwise unreachable points. Image width is 600-m across, north is up, and the boulder in the lower left-hand corner is 15-m across, unnamed 15-km diamater crater southwest of Rowland crater [NASA/GSFC/Arizona State University].

Distinctive asymmetrical ejecta surrounding a 140 meter diameter crater in the lunar highlands. Crater is located on the northeastern rim of the eroded (pre-Nectarian) crater Hommel at -52.9° N and 34.6° E. Image width is 600 meters and north is up, 0.6 m/pixel resolution [NASA/GSFC/Arizona State University].

Crater (center of image) formed by impact of the Apollo 14 Saturn IVB booster. The booster was intentionally impacted into the lunar surface on February 4, 1971 to serve as an energy source to probe the interior structure of the Moon using seismometers placed on the surface by Apollo astronauts [NASA/GSFC/Arizona State University].

Two oxbow bends along the length of a sinuous rille located on a mare-filled crater floor. The tight twists and turns of the rille suggest that a very turbulent lava flow formed this rille. Subarea of uncalibrated LROC NAC frame M102672335L; image width is 1.56 km across and north is up [NASA/GSFC/Arizona State University].

Subset of uncalibrated LROC NAC frame M104447576R showing Vallis Lorca, one of four lobes that make up Aratus CA in western Mare Serenitatis near the Montes Apennius. The Sun is shining from the lower left, image width is 1924 meters [NASA/GSFC/Arizona State University].

Surveyor 1 spacecraft sitting silently on Oceanus Procellarum, the first US spacecraft to land on another planet (June 2, 1966). The image was taken in the lunar afternoon such that the sun in low on the western horizon and the 3.3 meter tall spacecraft casts a long shadow (almost 15 m long) to the east [NASA/GSFC/Arizona State University].

The linear rille Rima Ariadaeus is found on the nearside of the Moon, nestled between Mare Tranquillitatis and Mare Vaporum. Most linear rilles are believed to represent tectonic faulting and can be used to determine stratigraphic relationships on a surface. Image width is 1.2 km [NASA/GSFC/Arizona State University].
