Plain of Jars second site

The jars are huge, up to nine feet tall, the largest weighing 14 tons. Most are carved of sandstone, others of granite, conglomerate, or calcified coral. Some are round, others angular, and a few have disks that appear to be lids. Tools and human remains found inside and around the jars suggest their use and manufacture spanned centuries. The bulk of material dates from 500 B.C. to A.D. 800, and additional carbon dates are expected this summer.
