Ancient footprints found at Tucson road construction site [View all]

TUCSON — A worker excavating the planned site of a bridge and new interstate connection on the city’s northwest side has unearthed an archaeological find that is believed to date back more than 2,500 years.

Dan Arnit of Innovative Excavating was working at the site of the planned Sunset Road connection to Silverbell Road just west of Interstate 10 when he came across something startling — prehistoric human footprints, possibly the oldest set found north of Mexico in the Southwest.

“I saw what looked like a heel,” he said.

Arnit found the footprints stamped into the mud of an ancient irrigated field, dried solid and covered with sediment some 2,500 to 3,000 years ago.
