Eponym	William T. Olcott

Olcott is a relatively fresh crater on the far side of the Moon. It lies to the south-southeast of the craters Seyfert and Polzunov, and to the north of Kostinskiy.

This crater lacks any significant appearance of erosion from subsequent impacts, and its features are relatively well-defined. The rim edge is generally circular, with a slight outward bulge to the northeast and a larger bulge to the south. It has an outer rampart and some terraces and slumped edges along the inner wall. Several low ridges lie near the interior mid-point, with the western pair near the center and the eastern peaks offset towards the eastern rim.

The satellite craters Olcott M and Olcott L form an overlapping pair along the southern outer rampart of Olcott, with the smaller member of the pair Olcott L overlapping Olcott M. The satellite crater Olcott E is partly overlain by the eastern rim of Olcott.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Olcott.
