Comparative Geology of Crater Aratus CA (Mare Serenitatis) and Bear Crater (Idaho)
Greeley R. 1973. Comparative Geology of Crater Aratus CA (Mare Serenitatis) and Bear Crater (Idaho). In Lyndon B. Johnson Space Center. Apollo 17 Preliminary Science Report. Scientific and Technical Information Office, NASA. Washington DC
Geology of Bear Crater is described in comparison with the lunar crater, Aratus CA. Geographic location: Bear crater is 45 km south-southeast of CRMO (Craters of the Moon National Monument) Aratus CA (lat. 24.5 N, long. 11.3 E) is an irregular-shaped crater 8.6 km long by 3 km wide in western Mare Serenitatis, which was photographed during the Apollo 15 and 17 missions. It is similar in form to Bear Crater (fig. 30-2), a small volcanic vent formed in Holocene basalt flows of the Snake River Plains, Idaho. The two features are compared and it is concluded that Aratus CA may have a geologic structure and history similar to that of Bear Crater.
