Sample Type 2:	Flow
Field Lithology:	Basaltic Andesite

Text Description:
Massive basaltic andesite flow. Massive flow or flows of dense to vesicular basaltic andesite exhibiting pronounced columnar jointing. Rocks are dark gray to black and contain abundant olivine phenocrysts in a fine-grained intersertal to intergranular matrix. Unit caps north end of Lakes Plateau. Source is probably local.
