USGS-issued map of the region around the Aristarchus Crater, the brightest of the large formations on the moon's surface. The map shows the types of various formations that appear, as identified by pre-Apollo geological investigations of the moon's surface. This work was compiled by H. J. Moore and published in 1965.
The main map shows over twenty formations, most related to craters of various ages. Below this are two cross-sections taken through the moon's surface. In the lower right is an inset showing where this crater is located on the near side of the moon.
