Lithology and environment
Primary lithology:massive,red sandy siltstone
Lithology description: The dominant lithology of the lower part is massive, pinkish brown sandy silt and sandy clay; ledges or lenses of hard, blocky-weathering, gray sandstone alternate with beds of light-colored, non-resistant sandstone. These hard layers are not persistent but occur at varying levels as hard, sheetlike lenses.
Environment:fluvial indet.
