| description (summary) | 2003-8-16 | jl | This photo shows the developing white layer in k31. This lends support to the hypothesis that the white layers which had previously been observed only during excavation of the mud ledge f423 were in fact accumulation pressed up against the ledge, rather than a part of the ledge itself. The white material seems to be decayed plant material. | [Input File: N816jl.j] |
