To persistent brown orange-red weathering 'lozylm' sophirizon cones, (About 1/2 way up zone scattered) Lozylc plstery ss cones with Trus(10?) Cones at top are 2 kinds, both generally small 1-1 1/2 bright orange + red, avoid types, and grey brown more medium, generally smaller kind. Covered to study shale interval capped by lozylc sophirizon. This appears to be the "upper" lozylc of our localities. Locy/fossile cones zone small . grey sophirizon just above it, or between them. Dk grey silty shale, scattered rusty wealth cones - small to 2' dim flat avoid. Loc with Trus & priovotrophic In upper 2' many red orange weather cones 1-2' dim int break to shreds + cone shely slope below. Locally some very large cone masses, this level. Loc. fossile. -Trus
