Alder (crater)

Alder is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It is located in the South Pole-Aitken basin, and lies to the southeast of the crater Von Kármán. Southeast of Alder is Bose, and to the south-southwest lies Boyle. Alder is associated with the only area in the basin not dominated by the pyroxene rocks typical of lunar lowlands. This alder ejecta area is on spectrographic evidence instead principally anorthosite rock, typical of the lunar highlands.
