The Plato quadrangle in north-central part of the Moon lies within a series of concentric depress ed and raised rings surrounding the Imbrium basin, the center of which lies about 335 km southwest of Montes Teneriffe . The innermost raised ring is marked by isolated ridges and peaks within Mare Imbrium itself, including in the Plato quadrangle Montes Recti and Tener iffee . The band of terra including Montes Alpes form part of the second and most prominent raised ring, immediately encircling Mare Imbrium . Mare Frigoris is part of the succeeding depressed ring and the terra i n the north of the quadrangle part of the third surrounding ring. It is believed that the Imbrium basin and other multi-ringed basins on the Moon were formed by the impacts of larger bodies (Baldwin, 1949 p. 200-216; Hartmann and Kuiper, 1962; Shoemaker and Ha ckman, 1962; Wilhelms and McCauley, 1971).
