crater's
Volcanic depression's rim
Crater's is the possessive form of crater—a bowl-shaped depression, typically formed by impact or explosion.
A meteor crater's rim, a volcano crater's depth, a bomb crater's diameter.
The word also applies to similar shapes: The crater's edge was lined with coffee residue.
