| Includes fossils? | Y |
| Lithology description: pelmicrite/mudstone, "thin, flaggy limestones"; "Calcarenite, foraminifera-ostracode packstone at base grades up to calcarenite, ostracode-miliolid wackestone in middle and grades up to calcilutite, lime mudstone at top; thin bedded flaggy limestone (Y." to 2" flags), rare gastropods, bivalves and foraminifera also present, worm trails and mudcracks common in and near track layers, small calcite filled voids-former evaporite nodules." | |
| Environment: | terrestrial indet. |
| Geology comments: "stromatolitic hard crusts, root marks, mud cracks and birdseye structure indicating tidal flat deposits...Ripple marks, current streaks, fine planar cross beds, and flat mud clasts are scattered throughout member... dolomitic sediments once contained gypsum" Tracks probably made on exposed flats | |
