Geological Chronicle
Winlock is a lunar impact crater on the far side of the Moon, where it lies to the west of the large walled plain called Lorentz. The formation spans an official diameter of 63.93 kilometers.
From the Earth this crater is located behind the northwestern limb, and just beyond the parts of the far side that are sometimes brought into view due to libration. It is recorded in the IAU Gazetteer under quadrangle LAC-36.
