Monday, March 19, 2007 Modern Technology Reveals Ancient Footpaths Buried in 2,500 Years Worth of Volcanic AshCentral-American villagers created sacred burial customs despite volcanic eruptions Washington, D.C. - infoZine - More than 20 years ago, volcano scientists Payson Sheets and Tom Sever teamed up to solve a mystery. While flying over the active Arenal volcano in the mountains of Costa Rica, infrared imaging technology on board their research plane picked up a steady trail--one with a beginning and an ending--concealed deep within the earth. The trail showed a clear path away from what Sheets and Sever knew to be ancient...

During the past two years, a team of graduate students, NASA archaeologists and remote sensing specialists led by Professor Payson Sheets spent much of their time mapping the small footpaths, many of which are invisible on the ground but visible by satellites. The...
