just east of the historical residential part of town. It lies along the southern margin of the Horseshoe Lake meander just north of the East St. Louis Mound Group of earthworks. By the end of the 2007 field season, the team had excavated 7,000 prehistoric features, making this one of the largest sites ever excavated in the USA. Most of these features are associated with the Late Woodland Patrick phase and early Terminal Late Woodland Lloyd phase, approximately from 600 AD to 1200 AD. They suggest a more complex and dense indigenous community than researchers had known lived in the area. In association with its work, the Illinois State Archaeological Survey (ISAS) (formerly ITARP), a joint project of the state and the University of Illinois, conducted outreach with the village of Brooklyn, volunteering to survey some of the areas associated with its early 19th-century history. A team of archaeologists led by Dr. Joseph Galloy found evidence of early Afro-American occupation from 1830 to 1850, as well as material in other areas from 1850 to 1870. This discovery suggests that the remains of Mother Baltimore's Freedom Village survive beneath the surface in Upper Brooklyn. It also means that artifacts and other evidence of the town's founding may be revealed if additional excavations are conducted there in the future. This would enhance the town's historical significance and research potential. Since the turn of the 21st century, residents have rallied around new work related to documentation of the village's rich historical past. They have worked to collect oral histories and personal accounts of the village. In 2007, residents founded the Historical Society Of Brooklyn, Illinois. The historical society, together with the ISAS' Drs. Joseph Galloy, Thomas Emerson and Miranda Yancey; Dr. Chris Fennell of the University of Illinois, and the Illinois State Museum, is working to preserve the history of Brooklyn. ISAS also helped the historical society to review documents to locate "Mother" Priscilla Baltimore's unmarked grave at Bellefontaine Cemetery in St. Louis. In September 2010, the Brooklyn Historical Society installed a gravestone in her honor at the cemetery. In addition, ISAS will assist the village in surveying the Brooklyn cemetery to detect gravesites and try to document the history. Surveys in 2008 revealed that "the archaeological record of Brooklyn lies intact beneath the extensive open spaces of current-day residential parcels." In the summer of 2009, an archaeological field study began to excavate
