Distinctive reddish-range, compact fill of a cut (SU418) cut partially into the layers above (SU414) and partially into the bedrock. The fill covered a pile of irregular tufo stones (SU424) and another layer (SU425) composed of a gravely, gritty gray soil with more inclusions. The layer may be the remains of a decomposed tree (tree bole) planted in the cut (SU418) on top of the stones (SU424). The composition of the reddish-orange fill and stones is very similar to that from the 'hut' of 2009 (orignally thought to be a hearth, later thought to be a possible tree bole).
