SAMPLE INFO : AL09-03PM

Sample ID:	AL09-03PM
Station ID:	AL09-03
Latitude:	53.88707
Longitude:	-166.93202
Datum:	NAD83
Date Sampled:	2009-00-00
Sample Type 1:	Tephra Fall

Text Description:
Middle Pumice is 10-115cm thick layer of moderately well-sorted, ungraded vitric lapilli and fine blocks. The most abundant clast-type is brown-beige pumice, which occurs as lapilli and bombs as large as 15cm in the long dimension. PM also has sparse, smaller lithic fragments (5 wt% of layer) that are both vitric (60% of lithics) and vairably altered volcanic lithologies (40% of lithics)
