Montes Jura

Montes Jura

Montes Jura is a mountain range in the northwest part of the near side of the Moon. The selenographic coordinates of this range are 47.1° N 34.0° W. It has a diameter of 422 km, with mountains rising to approximately 3800m above the level of Sinus Iridum. They were named after the Jura Mountains in eastern France / western Switzerland.This range of mountains form a visually pleasing semi-circular ring around the Sinus Iridum, a bay along the northwestern edge of Mare Imbrium. The blunt, east-facing cape at the southwestern end of the range is named Promontorium Heraclides, while the east-facing wedge at the northeast end is called Promontorium Laplace. As the terminator advances near this range two to three nights after the first quarter moon, the peaks of this range catch the sunlight at their tops. This produces a string of bright points that have been described as the 'jewelled scimitar' effect.The only crater of note in this range is Bianchini, which lies across the north-northwestern portion of the curve. A little farther to the west is Sharp, and to the northeast is the ruined crater Maupertuis. Peter Grego describes a figurine of "The Moon Maiden", seeing her facial profile in Promontorium Heraclides, her hair in the hills to the west, and her body in Montes Jura. She appears upside down when viewed in binoculars from the Northern Hemisphere.
