If by crater you mean having a "local minimum", then the L4 and L5 points are actually like that and can even capture asteroids: https://en.wikipedia.org/wiki/

  Hm, I cannot unify that claim with this diagram: https://en.wikipedia.org/wiki/Lagrange_point#/media/File:Lagrange_points2.svg https://en.wikipedia.org/wiki/Lagrange_point#/media/File:Lag...

    From that wiki page: >Although the L4 and L5 points are found at the top of a "hill", as in the effective potential contour plot above, they are nonetheless stable. The reason for the stability is a second-order effect: as a body moves away from the exact Lagrange position, Coriolis acceleration (which depends on the velocity of an orbiting object and cannot be modeled as a contour map)[20] curves the trajectory into a path around (rather than away from) the point.[20][22] Because the source of stability is the Coriolis force, the resulting orbits can be stable, but generally are not planar, but "three-dimensional": they lie on a warped surface intersecting the ecliptic plane. The kidney-shaped orbits typically shown nested around L4 and L5 are the projections of the orbits on a plane (e.g. the ecliptic) and not the full 3-D orbits.

      Damn astronomy is crazy. And the point still stands!
