BRIEF DESCRIPTION
58.7_N_146.1_W_
Birkhoff is Ridge Section 82 named after the giant 345 km lunar walled plain located on the lunar Far Side's northern hemisphere. This formation is an ancient impact site that has been heavily eroded, and the surface reshaped by multiple craters in the interior and along the rim. The outer wall is bordered by the craters Carnot to the south and Rowland (Section 81)  along the west rim. What remains of the perimeter is now a rugged sloping rise along the inner wall, and the rim has been worn down until it is level with the irregular external terrain. The rim is pock-marked by small craters of various dimensions. Within the crater are several craters that are notable in their own right. Along the northwest inner rim is the eroded Birkhoff X, while due south in the southwest floor is Birkhoff Q. The later is joined by a low ridge to the double crater formation of Birkhoff K and L in the eastern half of the crater. In the northern interior are the smaller but relatively young Birkhoff Y and Z. The remainder of the floor is flat in places, with rough sections and many tiny craterlets. (Credit: Some of the information used in the section feature descriptions was obtained from wikipedia.org.  Section 82 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
