TAC SITE SPOTLIGHT, SOUTHEAST REGION: Filhiol Mound is a Coles Creek/Plaquemine period mound located near Monroe, Louisiana, on a natural levee of the Ouachita River. The land was once part of the Filhiol Plantation, and an 1850s cemetery on the summit helped preserve the mound.
TAC SITE SPOTLIGHT, The Woodhaven Archaeological Preserve in Washington was excavated from 2007 to 2011 ahead of a residential development. The site was ultimately preserved after work showed its significance as a pre-contact village and quarry dating to 8,700–7,400 years ago in the Olcott Complex.
