Named after the Altamaha River. The type name was originally called King George Malleated in Joseph Caldwell's Master's thesis, but was changed to the present name by his wife Sheila based upon her excavations at Fort King George in the early 1950s. Once thought to be a series of cross simple stamp designs. We now recognize that Altamaha Cross Simple Stamped and Altamaha Line Blocked are two distinct types.
A line block design on grit-tempered pottery.
