  • Why do creationists keep saying carbon dating is with a layer of volcanic ash, and volcanic material allows for other types of dating (potassium-argon).
  • The stratigraphy is extremely deep and layers of volcanic ash and stones allow radiometric dating of the embedded artifacts, mostly through potassium–argon dating.
