and locally shows weathering out of ss in fo re-enforced joint zones. Platy ss holds eastern ridge, which is locally the higher. Some cql at base - typical chert pebble stuff. Swale in E ridge on v.v.r. beds between top ss and Lytle-like ss. In this zone - from near- top (W side) polished pebbles are weathering. None such in basal cql of upper ss. None seen in place, but it is exactly same position as at Como Bluff. Here no big chert ledges evident, but huge pieces of some chert as at Como, some in root-weather. concs, some in pebbles, where pebbles not as smoothly rounded as others in zone.
