0252 - Evaluating the effort 1

Outeiro Alto 2 is a small ditched enclosure. It has just one ditch with a perimeter of 101m. If the size of the ditch is regular (as the two opposite surveys suggest) it will have a volume of 254 m3, corresponding to 406 tons of extracted rock (1600kg per 1m3, as average for limestone rock). That rock is not in the site: not outside the ditch and not inside the ditch (as it would be expected if there was a bank built with the extracted material). This is a common situation in Portuguese Ditched Enclosures, big or small.
