Vesicular basalt. Ferrosaponite from this locality seems to be ordinary iron-bearing saponite. No data available to justify ferrosaponite from this locality.

DeVito article states that the site consisted of series of three andesitic flows. The bottom zone was "a intermediate volcanic tuff with considerable glass [...] devitrified and altered to clays and zeolites", reported rich in philipsite and offretite . The middle zone was "a gray-black brecciated glass-rich porphyritic andesite" with many zeolites. The top flow was "a dark dense glass-rich brecciated basaltic andesite" with calcite and no zeolites.
