Border Patrol officials in Arizona say they’ve found no cultural or biological sites within a swath of border land currently being blown up to make way for a new border fence.
Sector chief Roy Villarreal tweeted out this video Thursday morning showing the desert ground jump as it was rattled by the latest explosion.
Villareal declined to be interviewed through a spokesman and said on Twitter that the detonations are happening in areas disturbed by the last border fence project.
Archaeologists have said Monument Hill at Organ Pipe Cactus National Monument where the explosions are taking place has been used as a burial site in the past.
