Erased from the pages of time, these cultures discovered and charted the heavens, developed earth-centric sciences and unleashed advancements that parallel and, in many cases, surpass our own.

Drawing on archaeological excavations, early antiquarian accounts, and modern scientific analysis, this book examines Adena burial mounds, earthworks, village sites, and material culture in clear, accessible detail. Designed for students, avocational archaeologists, historians, and anyone fascinated by ancient North America, ADENA: Mound Builders of the Ohio Valley Volume II, bridges technical research and public understanding. Volume II catalogs a wide array of Adena archaeological sites, providing detailed information from excavations and data sets. More than a catalog of mounds and artifacts, Adena: Mound Builders of the Ohio Valley Volume II, offers a thoughtful synthesis of what is known—and what remains uncertain—about a formative culture whose earthworks still shape the landscapes of the Eastern Woodlands. Jason Pentrail is an author, researcher, and host of the Seven Ages Audio Journal Podcast. He has extensive experience in archaeological excavations and documentation and is a military veteran of 20 years. https://sevenages.org/ Become a supporter of this podcast: https://www.spreaker.com/podcast/earth-ancients--2790919/support .","meta_description":"ADENA: Mound Builders of the Ohio Valley, Volume II, examines the archaeological record associated with the Adena culture throughout the Ohio River Valley…","key_points":[],"chapters":[],"topics":[],"duration_seconds":6825,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/earth-ancients-391184/episodes/jason-pentrail-adena-mound-builders-of-the-ohio-valley/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/earth-ancients-391184/jason-pentrail-adena-mound-builders-of-the-ohio-valley.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
