Description: Elger

(IAU Directions) DAWES.--A ring-plain 14 miles in diameter, situated N.E. of Plinius, on a nearly circular light area. Its bright border rises to a height of 2,000 feet above the Mare, and includes a central mountain, a white marking on the W., and a ridge running from the mountain to the S. wall. There are two closely parallel clefts on the N. side of the plateau running from W. to E., that nearer Dawes being the longer, and having a craterlet standing upon it about midway between its extremities. At its E. termination there is a crater-row running at right angles to it. The light area appears to be bounded on the W. by a low curved bank.

  • Slightly north of Dawes is a curious system of three rimae and a short craterlet-chain. This system is described and depicted in NASA SP-362, APOLLO OVER THE MOON; A VIEW FROM ORBIT, Chapter 5: Craters (Part 3), Figure 135. The exact location of the system is 18°20' North/ 26°15' East.
