Displacement & Tenure
Cession 11: Treaty of Greene Ville (1795); attorney Hugh Taylor Birch donated the initial 700-acre parcel to Antioch College in 1929 as a memorial to his daughter Helen Birch Bartlett; Glen Helen Association assumed operational ownership from Antioch College in 2020 via a $2.5 million agreement over ten years.
Shadow History
Frank Van Wort partially excavated the Orators Mound within the preserve in 1953 to 1954, finding five skeletons (two adults, three infants) and placing seven skeletons along with artifacts in the Dayton Museum of Natural History; Van Wort published no reports; the current location or repatriation status of this material is not confirmed in available sources; a 1971 Antioch College excavation under archaeologist Wolfgang Marschall identified the mound as Hopewellian; the Neff family's 246-room hotel at the Yellow Spring, built in 1869 at a cost of approximately $250,000 and targeting Southern vacationers, failed financially within 13 years.
