Pictured above are gigantic sandstone boulders in a gravel pit near Rosie Arkansas. While these house-sized boulders are not unusual, they’re location is: there is no nearby source for them. Some geologists speculate that they were transported to this location by a great tsunami generated during a major meteorite impact. Perhaps the same meteorite that caused that tsunami created the 110 mile diameter Chicxulub crater on the Yucatan peninsula about 65 million years ago.
