Stratigraphic studies: Part B: geologic setting of the dark mantling material in the Taurus-Littrow region of the Moon Stratigraphic studies: Part B: geologic setting of the dark mantling material in the Taurus-Littrow region of the Moon
A dark-colored surficial deposit covers lowlands and highlands along the southeastern margin of the Serenitatis basin. Sampling of this material was a major exploration objective of the Apollo 17 mission. Since completion of the mission, the dark mantle has been the subject of considerable controversy, inasmuch as no obvious stratified deposit was found in the landing area. Yet the...

Apollo lunar sounder experiment Apollo lunar sounder experiment
The scientific objectives of the Apollo lunar sounder experiment (ALSE) are (1) mapping of subsurface electrical conductivity structure to infer geological structure, (2) surface profiling to determine lunar topographic variations, (3) surface imaging, and (4) measuring galactic electromagnetic radiation in the lunar environment. The ALSE was a three-frequency, wide-band, coherent radar...

Remote sensing and photogrammetric studies: Part C: comparison between photogrammetric and bistatic-radar slope-frequency distributions Remote sensing and photogrammetric studies: Part C: comparison between photogrammetric and bistatic-radar slope-frequency distributions
Stereoscopic photographs taken by the metric and panoramic cameras can be used to obtain information on the roughness and slope-frequency distributions of lunar surfaces (see appendix to this part). Bistatic radar on board Apollo 14, 15, and 16 spacecraft may also be used to obtain information on lunar surface roughness at two wavelengths—13 cm (S-band) and 116 cm (VHF).

Documentation and environment of the Apollo 17 samples Documentation and environment of the Apollo 17 samples
This catalog shows the locations from which samples were collected during the Apollo 17 mission and provides a descriptive geologic context for each sample. It is a working document principally of use to LSPET, LSAPT, and the lunar sample principal investigators. The information in this report is incomplete, but it is based on the best available data as of January 19, 1973. Sources of...

The landslide at Cumberland, Harlan County, Kentucky The landslide at Cumberland, Harlan County, Kentucky
A landslide developed on Sanctified Hill, on the east side of Cumberland, Kentucky on December 10, 1972. Since then the slide has rendered 17 dwellings and a church unusable. The slide is in a shallow amphitheater, on plastic sandy clay up to 30 feet thick, lying on top of sandstone and shale (Norton Formation). The bedrock dips 22° south, the same direction as the slope of the hill. The...

Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows
Orbital photographs taken at low-Sun illumination during both the Apollo 15 (ref. 30-14) and Apollo 17 missions have provided excellent data on the lava flows in the southwestern Mare Imbrium. These photographs have been used recently to present a detailed photogeologic evaluation of these flows and their role in mare volcanism of Eratosthenian age in the basin (ref. 30-15). Eruption of...
