Ceren (IMAGE) University of Colorado at Boulder Caption An ancient Maya white road known as a sacbe has been discovered buried under roughly 17 feet of volcanic ash at the archaeological village of Ceren in El Salvador by a University of Colorado Boulder team. The sacbe, shown here with a drainage canal on the left and several corn plants preserved by ash on the right, is roughly 1,400 years old and is the only sacbe ever discovered constructed without stone linings.
