An extinct volcanic crater on Easter Island which served as a quarry for the stone statues (moai) which were erected in rows on the many ahu on the island. The rock is a soft tuff and the main usage of the two quarries, one inside and one outside the crater, dates to between c 1000-1500 AD. The site is filled with almost 400 unfinished statues and with many finished moai erected. Thousands of basalt handheld picks were discarded at the site.
