To the east and west, both valleys are flanked by parallel mountain ridges that locally run north to south, but are a part of a larger system of ridges that generally runs north-east to south-west (the tailing ends of the Appalachian foothills). The valleys are drained by small creeks (Buck Creek, Beaverdam Creek) which flow into the Cahaba River.

George L. Scott, Sr., an Alabaster pioneer, owned and operated Alabaster Lime Co. His shipping point was known as “Scott Rock.” Later, housing was built to accommodate some of the employees, and the community acquired its name Alabaster from the "white calcium carbonate mineral." The First Bank of Alabaster opened in 1952, and its president was George L. Scott, Jr., who later became the first mayor of Alabaster. The first attempt in 1952 to incorporate Alabaster failed. In January 1953, the petition was again filed, and on February 23, 1953, Alabaster was officially incorporated with a favorable vote of 79 to 23, and 427 residing inhabitants.
