The study, recently published by Dorsey Hager (1953), prompted the writer to revisit Meteor Crater, Arizona, as well as the main Odessa meteorite crater, in western Texas, and to evaluate certain structural differences. The structural features of these craters have been described previously (Barringer, 1910; Hager, 1953; Merrill, 1908; Sellards and Evans, 1941, et al.,).

Structural differences.—The main Odessa crater is markedly circular due to deformation of the rock strata following meteoritic impact. Segments of the rim have been thrust outward. Meteor Crater, on the other hand, exhibits a pronounced linear aspect...
