| Stratigraphy comments: The lower 200 ft of Oclese Sand consists of lightly weathering tuffaceous very fine grained silty sandstone with scattered calcaerous sandstone concretions. Maximum thickness of the formation is approximately 1400 ft. Grades laterally into siltstone of the underlying Freeman Silt and is overlain by the Round Mountain Silt. | |||||
