Lab sample # 11N00566; observed in pit, small. Due to the nature of the reclaimed material this horizon also contained strong coarse angular blocky structure. When this structure was added to the horizon, Nasis 6 recognized this horizon as two separate horizons. So it was removed and added to the text notes. Occasional cobbles and stones are found in this horizon
