Lab ID:IA-11
Comment:The remaining material can be found in the border of a drainage. It can be seen in the satellite image to the east of the sample. Thickness is decimetric. The ash filled a drainage cHannel when it deposited. That´s why we find it at the margins of the drainage channels. Sometimes it is cemented in the external face forming a hard crust. It appears not to be reworked.
