Monoliths embedded deep in ground substrate. Monoliths embedded deep in ground substrate Cross-section shows different stone types: monoliths, large vertical slabs, small vertical slabs, angular blocks, pebbles for stabilization, and horizontal slabs Structures approximately 2 meters high (close to 7 feet)

What are fish weirs? These clever structures funnel fish into corralled areas. Used by ancient and modern cultures, including Native Americans on the Pee Dee River & Columbia River. Simple but effective fishing technology! 🐟🏗️

Key Facts

  • Monoliths embedded deep in ground substrate
  • Cross-section shows different stone types: monoliths, large vertical slabs, small vertical slabs, angular blocks, pebbles for stabilization, and horizontal slabs
  • Structures approximately 2 meters high (close to 7 feet)
  • Structures approximately 15-21 meters wide
  • Asymmetry in Taffoni structure suggests multiple construction phases or repurposing
  • Monoliths likely erected first, then stabilized with rubble and angular blocks
