I think that the impact hypothesis is wrong because the city-size asteroid grazed the earth, thus left Iridium scattered over an area of New Mexico, AZ, toward gulf region. The asteroid bounced off earth. The deposits of Iridium are wide as it entered earths atmosphere which explains the spread Iridium over large area in heavy concentrations in those areas.The lack of evdience of full impact depth this would have created somewhat differnt damage which we see, The asteroid is heading away from earth as we speak. google can’t find it..
