The Mississippian Borden Formation is a mapped bedrock unit in a state that was originally part of what other state?
Borden Formation The Mississippian Borden Formation is a mapped bedrock unit in Kentucky, Indiana, Illinois, Ohio, West Virginia, and Tennessee. It has many members, which has led some geologists to consider it a group (for example in Indiana) rather than a formation (for example in Kentucky).
Florida Panhandle The Florida Panhandle, Northwest Florida, or West Florida, an informal, unofficial term for the northwestern part of the U.S. state of Florida, is a strip of land roughly 200 miles long and 50 to 100 miles wide (320 km by 80 to 160 km), lying between Alabama on the north and the west, Georgia also on the north, and the Gulf of Mexico to the south. Its eastern boundary is arbitrarily defined. The terms West Florida and Northwest Florida are today generally synonymous with the Panhandle, although historically West Florida was the name of a British colony (1763–1783), later a Spanish colony (1783–1821), both of which included modern-day Florida west of the Apalachicola River as well as portions of what are now Alabama, Mississippi, and Louisiana.
