A 25-foot-wide, nearly 8-foot-deep pit carved into Göbekli Tepe's bedrock may have served as a cistern, while a carved channel found about 150 yards away was identified as early plumbing for collecting rainwater.
Notes on verification
Confirmed by original archaeology.org article, peer-reviewed DAI publication (Clare 2020), and independent academic review (Open Archaeology 2022), plus Wikipedia's sourced summary. Core findings (bedrock cistern, rainwater channel) well corroborated; specific dimensions/distance trace to a single journalistic source but align with underlying archaeological data.
