This sacbé goes 62 miles to Yaxuna, near the later Chichen Itza. Sacbéob are raised, very level, white roads. Their flatness allowed for large stones to be moved on rollers. Their paving of white seashells allowed travelers to see better in dusk and by moonlight. Now trees grow there. (The site was cleared in the 1970s, and all these trees have grown since then.) Many sacbéob converge at Cobá.
