Ancient footprints of acahualinca radiocarbon dating
Today, the two archaeologists regularly dig in wave-washed places where no one else on the west coast thought to look before—and they are finding plenty of sites.The key to locating sites turned out to be an understanding of ancient sea level changes.After three days of digging through sand and gravel in a four-square-meter pit, Fedje reached the gray clay layer where he had spotted the strange shape a year earlier. Two footprints were side by side, others pointed in different directions; they were all near a stone-lined hearth.
They would also be just 1,300 years younger than the oldest footprints in the New World, which were found at the site of Monte Verde in Chile during a dig led by Vanderbilt University archaeologist Tom Dillehay.The new discovery on Calvert Island, Lockley adds, sounds “very interesting.” For Fedje and Mc Laren, the significance of the unexpected find is just starting to sink in.“To see those footprints, it’s really evocative,” marvels Mc Laren.“It’s something we can all relate to because it represents a brief moment of time.” On a sunny mid-May afternoon, Mc Laren leads the way across the shore at Ej Ta4, his heavy rubber boots leaving a trail of corrugated footprints.Sunburned and chapped, with wavy black hair flying off in all directions, Mc Laren looks a little weatherworn after three weeks in the field. He hustles up a 3.5-meter-high stepladder to the top of the site’s midden and spends the next five minutes effortlessly navigating a dense tangle of fallen conifers and gnarled tree roots before reaching a sheltered bay where sandpipers feed.
