Text Description: See sketch in book. Two breccias at base of wall, one coarse with pumice, one finer grained with laminations. Coarse breccia seems to be plastered on the finer breccia. Blocks of breccia in stream cut show clasts with "plag clots" in them. Also in stream bed are large blocks with flow textures. Flow bands wrap around lithics (Fisher?) Dike material, fairly rotten. Seemingly aphyric, black with blue-grey oblong discoid filled vesicles (?), possibly from weathering References: ![]() |
