Many questions about the famous moai statues on Easter Island, Chile, have long eluded scholars—from their cultural significance to how they were made and transported. A recent study in the Journal of Archaeological Science by archaeologists Carl Lipo of Binghamton University and Terry Hunt of the University of Arizona poses the theory that the 92-ton statues were transported in a vertical position, with movers using ropes to “walk” the moai across the island and onto their ahu, or platforms. This theory is supported by the oral traditions of the island’s Indigenous Rapa Nui people, which reference the moai “walking” from...

The process of coastal groundwater discharge makes it possible for humans to collect drinkable freshwater directly where it emerges at the coast of the island... "The porous volcanic soils quickly absorb rain, resulting in a lack of streams and rivers," Lipo said. "Fortunately, water beneath the ground flows downhill and ultimately exits the ground directly at the point at which the porous subterranean rock meets the ocean. When tides are low, this results in the flow of freshwater directly into the sea. Humans can thus take advantage of these sources of freshwater by capturing the water at these points." ...He...
