Hand sample; >20g. Pumice lapilli in fall deposit or possibly pum-concentration zone in pf; near base of thick section of pfs; collection of pumice clasts, chiefly pinkish brown to brownish gray. On rounded, exposed surfaces all lapilli are ~20%k. Lapillus interiors from two dominant types. (1, CHEM SAMPLE) The most numerous (~80% of sample) are medium olive gray in the interior with faintly orange tinged rinds. These are vesicular and moderately porphyritic (xls ~ 1mm) with glassy groundmass forming glass threads spanning and surrounding some vesicles.
