The Fish Haven Dolomite is an Ordovician period geologic formation in southern Idaho, northeastern Nevada, and northwestern Utah. [1]
It was named for Fish Haven Creek, in the Bear River Range near the Utah-Idaho state line. [1] Other locations it is found in include the Schell Creek Range, Goshute Mountains, Deep Creek Range, Pilot Range, and Toana John Mountains. [1]
The Dolomite formation overlies the Eureka Quartzite formation, and underlies the Laketown Dolomite formation. [1]
The Fish Haven Dolomite, like the Ely Springs Dolomite, was formed by subtidal to intertidal shallow shelf carbonates, deposited in water depths of 100 feet (30 m) or less in lagoonal and shallow shoal settings. [1]
The formation preserves fossils dating back to the Ordovician period of the Paleozoic Era. [2]

The Powell Formation or Powell Dolomite is a geologic formation in northern Arkansas, southeast Missouri and Virginia. It contains gastropod, cephalopod, and trilobite fossils dating back to the Ordovician Period.
The Chepultepec Formation, is an Early Ordovician-age geological formation in the Appalachian regions of Eastern North America. Also known as the Chepultepec Dolomite, it is a unit of the Upper Knox Group, overlying the Copper Ridge Dolomite and underlying the Longview-Kingsport-Mascot sequence. The Chepultepec Formation is a primarily limestone and dolomite formation, the earliest formation of the Ordovician period in its area. Further north, it is equivalent to the Stonehenge Formation of the Beekmantown Group. The formation was first described from Allgood, Alabama, and has also been found in Tennessee and Virginia. Allgood was originally named "Chepultepec", providing its name to the formation as well. In Virginia, the Chepultepec Formation has a habit of forming large natural arches, including Natural Tunnel in Scott County and Natural Bridge in Rockbridge County.
The Cotter Formation is a geologic formation in Arkansas, Missouri, Oklahoma and in Virginia. It preserves fossils dating back to the Ordovician period.
The Tomstown Dolomite or Tomstown Formation is a geologic formation in Maryland, Pennsylvania, Virginia and West Virginia. It preserves fossils dating to the Cambrian Period.
The Everton Formation is a geologic formation in northern Arkansas that dates to the middle Ordovician Period. Unconformities separate this formation from the underlying Powell Formation and the overlying St. Peter Sandstone Formation. Named for the town of Everton in Boone County, Arkansas in 1907, the Everton Formation is composed primarily of dolomite, limestone, and sandstone.
The Saturday Mountain Formation is a geologic formation in Idaho and Iowa.
The Bighorn Dolomite is a geologic formation in Wyoming. It preserves fossils dating back to the Ordovician period.
The Manitou Limestone is a geologic formation in Colorado. It preserves fossils dating back to the Ordovician period.
The Notch Peak Formation is a geologic formation in Utah. It preserves fossils dating back to the Cambrian period.
The Ely Springs Dolomite is an Ordovician period geologic formation in the Southwestern United States.
The Crystal Peak Dolomite is a geologic formation in the Wah Wah Mountains of western Utah. It preserves fossils dating to the Middle Ordovician period.
The Laketown Dolomite is a dolomite geologic formation in Nevada and Utah. It preserves fossils dating back to the Silurian period.
The Wood Canyon Formation is a geologic formation in the northern Mojave Desert of Inyo County, California and Nye County and Clark County, Nevada.
The Goodwin Limestone is a geologic formation of the Pogonip Group in Nevada.
The Kanosh Formation is a geologic formation in Utah and Nevada. It preserves fossils dating back to the Middle Ordovician period.
The Lone Mountain Dolomite is a dolomite geologic formation in Nevada.
The Eureka Quartzite is an extensive Paleozoic marine sandstone deposit in western North America that is notable for its great extent, extreme purity, consistently fine grain size of Quartzite, and its tendency to form conspicuous white cliffs visible from afar.
The Broken Skull Formation is a geologic formation in Quebec. It preserves fossils dating back to the Ordovician period.
The Skoki Formation is a stratigraphic unit of Early to Middle Ordovician age that is present on the western edge of the Western Canada Sedimentary Basin in the Canadian Rockies of Alberta and British Columbia. It was named for Skoki Mountain near Lake Louise in Banff National Park by Charles Doolittle Walcott in 1928. The Skoki Formation is fossiliferous and includes remains of brachiopods and other marine invertebrates, as well as conodonts and oncolites.
The geology of Utah includes rocks formed at the edge of the proto-North American continent during the Precambrian. A shallow marine sedimentary environment covered the region for much of the Paleozoic and Mesozoic, followed by dryland conditions, volcanism and the formation of the basin and range terrain in the Cenozoic. Utah is a state in the western United States.
