Core 7

In this core, the top layer of soil below the humus appears to be highly weather, as it is light tan in color. Its possible this is slope wash or a weathered exterior surface. Below this is a rich organic layer, showing the third mound occupation surface. About 50 cmbs, we recovered another rich organic layer, which was immediately followed by basket loading. Around 227 cmbs we pick up a thin organic layer, followed by mound fill, and then another rich buried A around 250. Underneath this layer are natural soils. Rachel believes this mound was built on top of an older (allowed to weather) natural levee, thus indicating this mound was not built on an active water channel but possibly near an oxbow or old ridge/swale topography.
