…also noted the existence of small, shallow elongated depressions ("trenches" or "grooves") similar to those the Apollo 11 astronauts observed at Tranquility Base in the Sea of Tranquility; Shoemaker et al. preliminarily concluded in 1970 that these features reflected the direction and location of fractures in…

Lunar Orbiter 5 image from 1967, cropped to show the vicinity of the landing site of Apollo 11, used in mission planning. The image is centered precisely on a small crater called West crater (190 m in diameter), and the Lunar Module Eagle touched down about 550 m west of West Crater. The area shown is approximately 25 km × 25 km across.
