Given that we now have evidence that the circle k27 has a deeper elevation than the square k26, it is probable that this apparent vault was created by an inward and downward collapsing of the accumulation in k27. This caused the accumulation leaning against it, in turn, to fall inwards, explaining the vault-like bend inwards. It never needed to support itself; it was resting against complementary accumulation for its whole life. [Input: K731JL.j] |

okk suggests the term "mounding" which describes well what we see: as if the vault were a brick coating laid over a tumulus-like pile of ash/red soil. If so, f273, f259, and f258 would come first, then f303, then f306, f305, f304. The "vault" does seem to extend lower than f307. [Input: K627JL.j] |
