Geological Chronicle

Lacus Temporis, translated from Latin as the 'Lake of Time', is a small lunar mare situated in the northeastern quadrant of the Moon's near side. Spanning an overall diameter of 205.3 kilometers, the basaltic feature lies in the Geminus quadrangle at 46.77° N, 56.21° E.

The mare is composed of two large, roughly circular patches of relatively smooth surface, with a pair of small, cup-shaped craters located prominently at their intersection. Both regions of basaltic lava covered surface have smaller side lobes, which are most likely flooded impact features.

Just to the southwest of Lacus Temporis lies the crater Chevallier, while the crater Carrington is located to the southeast.
