当月亮处于初四分相时，从月球表面看，太阳沿着高加索山脉升起。在这张地球上的望远镜照片中，沿着月球的明暗分界线或月球的昼夜分界线，月球山脉投下了壮观的尖塔般的阴影。以地球自己的高加索山脉命名，崎岖的月球高加索山脉山峰，高达6公里，位于西部光滑的雨海和东部的宁静海之间。在这张第1 / 4的月球景观中，大部分仍处于阴影之中，在左侧（西部）的撞击坑反射着旭日的光线，沿着它们的外部，东部的陨石坑壁。

When the Moon is at its first quarter phase, the Sun rises along the Montes Caucasus as seen from the lunar surface. The lunar mountain range casts the magnificent, spire-like shadows in this telescopic view from planet Earth, looking along the lunar terminator or the boundary between lunar night and day. Named for Earth's own Caucasus Mountains, the rugged lunar Montes Caucasus peaks, up to 6 kilometers high, are located between the smooth Mare Imbrium to the west and Mare Serenitatis to the east. Still mostly in shadow in this first quarter lunarscape, at the left (west) impact craters reflect the light of the rising Sun along their outer, eastern crater walls.
