Qal DUNE SAND—Unconsolidated windblown sand formed into definite dune QdsQds structures and ridges Qds Pmw Qds Prs COVER SHEET SAND—Featureless sheet of windblown silt and sand Qcs Qcs

TERRACE GRAVEL—Unconsolidated gravel, sand, silt, and clay laid down Nog Qtg at several levels along former courses of present-day streams

Prs UNCONFORMITY OGALLALA FORMATION—Mostly unconsolidated to well-cemented, light Nog gray to light brown stream-laid deposits of sand, silt, clay, and gravel together with local caliche and volcanic ash. Where exposed, base usually consists of a well-indurated bed of conglomerate with basalt, limestone, and dolomite clasts

Pmw UNCONFORMITY CRETACEOUS UNDIVIDED—Chaotic mixture of large blocks of Dakota Kud and Cheyenne Sandstones intercalated with Kiowa Shale. Qal Formed from subsurface salt dissolution and collapse into older formations

UNCONFORMITY CLOUD CHIEF FORMATION—Reddish-brown to orange brown, Nog Pcc Nog locally greenish-gray shale locally interbedded with thin, reddish-brown fine- Kud grained sandstone and siltstone. Bedding usually chaotic due to slumping, Qal Kud calcite veining common. Base mapped at the Moccasin Creek gypsum bed

RUSH SPRINGS FORMATION—Reddish-brown, fine-grained Prs sandstone, commonly cross-bedded, with local interbeds of reddish-brown Kud Kud shale. Upper third of unit contains several thin gypsum beds

Prs MARLOW FORMATION—Usually a soft-weathering, orange- Pmw brown, fine-grained sandstone, with local interbeds of very sandy shale and siltstone

Kud DOG CREEK SHALE—Poorly exposed sequence of alternating Pdc Qtg reddish-brown shale, silty shale, and siltstone, with thin gypsum beds and Qtg stringers occurring throughout. Base mapped at top of highest massive Qtg Pcc Blaine gypsum bed Qal Pcc Qtg BLAINE FORMATION—Alternating sequence of four massive gypsum beds Qal Pcc Pbl with reddish-brown shale Qal Pcc Qtg FLOWERPOT SHALE—Reddish-brown silty shale; upper part with Pfp alternating thin gypsum beds underlying that give unit a characteristic striped pattern at a distance Qtg Qtg
