Summary:
Revised in that Redwall limestone unconformably overlies the newly named Muav limestone, upper formation of Tonto group in Shinumo quad, Coconino Co, AZ in the Plateau sedimentary province. Basal contact placed arbitrarily at base of alternating layers of calcareous sandstone and dense blue-gray crystalline limestone. This basal unit of Redwall is 110 ft thick. Overlying part of Redwall is composed of pure dense, blue-gray crystalline limestone that forms a single cliff, the highest in the Grand Canyon. Fossils listed. Underlies Supai formation of Aubrey group. Is 600 to 700 ft thick. Of Mississippian and Pennsylvanian age. Geologic map. Mapped on both sides of Colorado River.

Summary:
Upper contact revised. About 250 ft of red sandy shale, purple and gray limestone with red chert and red to buff calcareous sandstone is removed from the top of the Redwall and reassigned to the basal part of the overlying Supai formation. The name Redwall is thus restricted to the massive, gray, crystalline limestones that are of Mississippian age. Its upper and lower (with Temple Butte limestone) contacts are unconformities. Is 570+/-ft thick at Bass Trail which extends north and south of the Colorado River in Coconino Co, AZ in the Plateau sedimentary province.

Summary:
Lower contact revised. Redwall disconformably overlies the newly named Late Devonian Cove Fort Quartzite. Disconformably underlies the Pennsylvanian Oquirrh Formation. Mapped (geologic map) east of the Cove Fort on the southeast side of White Sage Flat, Millard Co, UT in the Great Basin province. Consists of thick, massive coarse crystalline oolitic limestone. Is 273 ft thick on east side of Sage Flat. Yielded Osagean age (corals, brachiopods, bryozoans, gastropod, forams) in the Pavant Range. Name Redwall extended into this area in preference to other Mississippian unit names because of the age of its fauna.

Summary:
Areally extended to southwest UT. Rocks formerly assigned (Butler, 1913) to the lower part of Topache Limestone in the report area are reassigned to the Redwall Limestone in this report. Mapped (geologic map) on west side of range, Beaver Co, UT, Great Basin province. Stratigraphic diagram. Contrasts with the overlying and underlying formations. The Redwall is a dark-gray to black, thick-bedded to massive limestone and dolomite with bedded and nodular chert and case-hardened limestone nodules. The underlying Pilot Shale is thinner bedded. The overlying Callville Limestone (the upper part of the Topache Limestone of Butler (1913)) is brown to red brown. Is 1,240 ft thick. Very fossiliferous--corals, brachiopods, ammonites, crinoids, bryozoans. Of Mississippian age.

Summary:
The name Redwall Limestone of Early and Late Mississippian age is extended northward from AZ into Kane Co, UT in the Plateau sedimentary province. Redwall unconformably overlies the Upper Devonian and Lower Mississippian Ouray? Limestone and unconformably underlies the Lower Pennsylvanian Molas Formation. The formation is divided in three parts (ascending): 1) Whitmore Wash and Thunder Springs Members, 232 ft thick; 2) Mooney Falls Member, 289 ft thick; and 3) Horseshoe Mesa Member, 160 ft thick. The Whitmore Wash and Thunder Springs are white, fossiliferous dolomite with white tripolitic chert. The Mooney Falls is a white to brown, crinoidal, cherty dolomite with a few thin brown limestone beds. The Horseshoe Mesa is a brown to white limestone with chert, and algal structures. The Early-Late Mississippian boundary lies within Mooney Falls Member. A marine deposit.

Summary:
Horseshoe Mesa Member of the [Mississippian] Redwall Limestone unconformably underlies the Watahomigi Formation (new) of the Supai Group (raised in rank from formation) at Watahomigi Point, Havasu Creek, Grand Canyon region, northern AZ in the Plateau sedimentary province. Upper surface is channeled with 5 ft of relief in 100 ft horizontal distance.

Summary:
Names applied in Grand Canyon area extended geographically to sequence in Big Maria Mountains of southeast CA in the Salton basin with change of lithic designation. Mississippian Redwall Limestone redescribed as Redwall Marble. Redwall consists of coarse-grained, massive, pure calcite marble, usually gleaming white. Is 0.2 to 50 m thick. Overlies Cambrian and Devonian unnamed dolomite marble; underlies Supai Formation. Equivalent to Escabrosa Limestone of southern AZ. This part of CA was part of stable craton of North America in Paleozoic and early Mesozoic time. Rocks were intruded by Middle Jurassic granodiorite and metamorphosed in Cretaceous time.

Summary:
New name Surprise Canyon Formation applied to rocks previously assigned to the Redwall Limestone and to Watahomigi Formation in the Grand Canyon area, AZ in the Plateau sedimentary province. Surprise Canyon is lithologically distinct from both the Redwall and the Watahomigi. Contact with the Redwall is unconformable and is placed at base of a cobble and pebble conglomerate above the limestone. Contact with Watahomigi is unconformable and is placed at the top of a thin gray ledge-forming limestone. Redwall is of Mississippian age.

Summary:
Redwall Limestone identified in subsurface of Black Mesa basin of northeast AZ where it can be divided into (ascending): Whitmore Wash Member (Kinderhookian and Osagean), Thunder Springs Member (Osagean), Mooney Falls Member (Osagean), and an upper or limestone unit (Meramecian). The Whitmore Wash unconformably overlies Devonian Martin Formation. The Mooney Falls is separated from the upper limestone unit by an unconformity. The end of Osagean is marked by a regional hiatus. The Meramecian-age limestone unit may be part of or equivalent to part of the Mooney Falls Member to the west or to the younger Horseshoe Member of the Redwall. The Redwall is overlain unconformably by unnamed redbeds and residuum. Correlation chart. The Whitmore Wash to Mooney Falls Members shown as equivalent to the lower part of the Leadville Limestone, and the Meramecian undesignated part of the Redwall is shown as equivalent to the upper part of the Leadville of the San Juan basin subsurface of northwest NM.
