 Text Description:
Located within a small depression characterized by vent facies on a nose at the very southern margin of Jaeger Mesa. 2A is nearly aphyric with the exception of an occasional acicular plagioclase phenocryst up to 3 mm in length. Oxidation is "mottled" throughout the blue-gray groundmass. 2B contains the same few acicular plagioclase phenocrysts, but in a highly vesicular "frothy" matrix. Small rounded clasts of vent material are visible within the sample.
