Text Description: Wrangell Lava. Source and age mostly unknown. Olivine basalts. Thick (greater than 5 m), medium-gray to medium-dark-gray, sparsely porphyritic flows containing phenocrysts of fresh olivine (trace to 5%, 0.5-2 mm) in an intergranular to intersertal groundmass of plagioclase, olivine, clinopyroxene, and locally glass. * * * Source for northernmost flows is apparently a small eroded shield volcano 2-3 km north in Nabesna C-6 quadrangle.
