1 :   
Comments: 6 bags approx 250 - 300 lbs, lab samples (3-4 pieces), 1 bag - lab samples. -fine grained vesicular basalt (100% of dredge contents); - apparent rounding (~ 1-2); - some pieces appear fresh (angular with testure); - basalts are olivine-phyric, some also have plagioclase phenocrysts. Vesicle size is very variable, but the overall impression is of one rock-type.
