If you draw an imaginary "X" from corner to corner and look very, very closely on the upper part of the "line" going from the center toward the upper left hand corner, a very short distance to the northwest of the rim and slightly left of the "line," you will see just barely discernable, a small impact in the surface. The same is true on the right hand line, going from the center toward the upper right corner. Look very closely and you will see five small impacts on the surface, with three in a row right next to each other just above and northeast of the crater. Probably fairly large hunks hit in those locations. If they have been explored or investigated or not is not know.
A specially processed image made by the airborne Thematic Mapper Simulator (TMS) shows that the ejecta blanket or apron (in reds and yellows) around Meteor Crater is asymmetrically distributed with maximum extension to the northeast. There is a notable tendency for the ejecta deposits to appear elongated to the northeast; probably an effect from wind-blown re-working or the angle/direction of impact. The ejecta contain fragments of the iron meteorite which caused Meteor Crater, along with iron melt spherules. The red and blue lines are power lines and roadways.
Sixty-five million years before the Meteor Crater impact a giant six-mile wide extinction-level object crossed into the Earth's atmosphere at an incredible high rate of speed. Within seconds the object slammed into a shallow sea in what is now the north coast of the Yucatan, Mexico with a force comparable to 100 million megatons of TNT. The impact created a crater 112 miles across and a tsunami wave two thousand feet high that swept as far north inland as the middle of present day Texas. The results of the impact caused the demise of entire species, including the dinosaurs. Ground zero for the asteroid was centered near today's small Yucatan town of Chicxulub, hence the name. See:
