Below Peat Stratum
Archaeologists knew there were more layers beneath the peat, based on a series of soil cores from the site. However, they could not reach these deeper strata before the field season ended. In spite of the difficulties of working at the site, the crew reached a depth of more than 9 feet, most of it below the water table!
