A Smithsonian trinomial (formally the Smithsonian Institution Trinomial System , abbreviated SITS ) is a unique identifier assigned to archaeological sites in many states in the United States . Trinomials are composed of a one or two digit coding for the state, typically two letters coding for the county or county-equivalent within the state, and one or more sequential digits representing the order in which the site was listed in that county. The Smithsonian Institution developed the site number system in the 1930s and 1940s, but it no longer maintains the system. Trinomials are now assigned by the individual states. The 48 states then in the union were assigned numbers in alphabetical order. Alaska was assigned number 49 and Hawaii was assigned number 50, after those states were admitted to the union. There is no Smithsonian trinomial number assigned for the District of Columbia or any United States territory.
7-397: The Ufferman Site (also known as the A. Sawyer Site , and designated 33DL12 ) is an archaeological site in the central part of the U.S. state of Ohio . Located north of the city of Delaware , it occupies approximately 2 acres (0.81 ha) of land near Delaware Lake on property near to the boundaries of Delaware State Park . It appears to have been the location of a village of
14-820: A historic district of three buildings ( Elliott Hall , Sturges Library , and Merrick Hall ) on the Ohio Wesleyan University campus in Delaware, the Spruce Run Earthworks near the village of Galena , and the Highbank Park Works near the city of Worthington — were listed on the Register before the Ufferman Site. Smithsonian trinomial Most states use trinomials of the form "nnAAnnnn", but some specify
21-407: A quadrangle, a sequential number within the rectangle, and a code identifying the agency issuing the sequential number. California uses a three-letter abbreviation for counties. Connecticut and Rhode Island do not use any sub-state codes, with site identifiers consisting of the state abbreviation and a sequential number series for the whole state. Delaware uses a single letter code for counties and adds
28-543: A space or dash between parts of the identifier, i.e., "nn AA nnnn" or "nn-AA-nnnn". Some states use variations of the trinomial system. Arizona, California, Connecticut, Maine, Rhode Island, and Vermont use two-letter abbreviations of the state name instead of the Smithsonian number. Alaska uses three-letter abbreviations for USGS map quadrangles in place of the county code. Arizona uses a five-part identifier based on USGS maps, specifying quadrangles, then rectangles within
35-566: The Cole culture , which inhabited the region during the later portion of the Woodland period . Ufferman lies only 0.6 kilometres (0.37 mi) south of the W.S. Cole Site , the type site for the culture, and approximately 23 kilometres (14 mi) north of the Highbank Park Works , which are believed to have been built by peoples of the Cole culture. Although archaeologists have never excavated
42-543: The Ufferman Site, numerous artifacts have been found because of the activities of local groundhogs . These animals favor the loose soil of the esker upon which the site lies, and their many diggings for their burrows have brought to the surface significant numbers of human and animal bones, pottery, and bits of stone. In 1974, the Ufferman Site was listed on the National Register of Historic Places because of its archaeological value. The primary importance of
49-626: The site is its ability to yield information about the Cole culture, which has been little understood until recent years. Fifty-five other historic locations in Delaware County are listed on the National Register, including four other archaeological sites. The Ufferman Site was one of the first of these places to be recognized as a historic site ; only four other places — the Delaware County Courthouse and
