Lunar 100 – Object 23
Mons Pico is an isolated mountain rising from the basalt plains of Mare Imbrium, standing as a solitary remnant of the basin’s inner ring. Its steep slopes and bright appearance contrast sharply with the surrounding mare, making it one of the most prominent landmarks in the region. Mons Pico is included in the Lunar 100 because it is a clear example of an isolated Imbrium basin‑ring fragment, showing how large impact basins can leave> behind scattered ring remnants as prominent mountains.
