During the 1990-91 academic year the Indiana State University Anthropology Laboratory (ISUAL) conducted four large- scale field projects. These consisted of a powerline corridor reconnaissance for Public Service Indiana (PSI), and excavations at prehistoric sites 12 Vi 42, 12 Sp 809 and 12 D 74.

The PSI reconnaissance involved the examination of a 64 mile-long (1200 acre) corridor in Kosciusko, Elkhart and Lagrange counties in northeastern Indiana. Landforms are predominantly of late Pleistocene origin and include end moraines, valley trains, outwash plains, dunes, kames and bogs. More restricted deposits of Holocene alluvium also occur. The reconnaissance resulted in the identification of 175 sites, of which over one-half were small, low density fire-cracked rock (FCR) scatters. Diagnostic artifacts representing 31 components were recovered from 24 sites. By temporal unit the components consisted of eight Early Archaic, six Middle-Late Archaic, three Terminal Archaic, two Early Woodland, one Middle Woodland, and five Late Woodland sites. In addition, 12 historic sites were recorded.

Sites occurred at a general frequency of one site per 4.52 acres examined. However, when examined by specific geomorphic features distinct differences in site frequencies were identified. The highest site density occurred on sandy Holocene alluvium (1 site/1.2 acres), followed by kames (1 site/1.4 acres), morainal rises (1 site/2.5 acres) and dunes (1 site/2.7 acres). Lower site densities occurred on till plain (1 site/4.1 acres), valley train (1 site/7.7 acres), and outwash (1 site/9.5 acres) features. Early Archaic and Late Woodland sites were distributed over a wide variety of landforms, while Middle, Late and Terminal Achaic sites tended to cluster on morainal and kame features.

For the second consecutive year the ISUAL conducted the High School Summer Honors Archaeology excavation at the Middle Woodland Halt site (12 Vi 42). This site is an Allison-LaMotte habitation located on a sand rise along Honey Creek some 4.5 km east of the Wabash River. Seventeen two by two meter units were hand excavated (a similar number of units were excavated in 1990) using standard procedures. The total excavated area of 132 square meters probably approaches 25% of the total site area. No subplowzone midden was identified, although light midden may be diffused in the plowzone. Twenty-one pit features have been identified, with most having functioned in the end as refuse pits.

Although no house patterns have been observed, the site appears to be a residential location occupied on a semi-sedentary or seasonal basis. The freuencies and types of features which occur in addition to the composition of the artifactual assemblage tend to support this interpretation. While the densities of fire-cracked rock and ceramics are high, only six Lowe points have been recovered. One feature (Feature no. 21) contained an entire reconstructible Embarrass series vessel, which is globular in form with a simple-stamped body and notched "pie crust" rim. Future excavations at the site are being planned.

Subsurface reconnaissance was conducted at site 12 Sp 809, an Early Woodland Crab Orchard site in the Ohio River bottoms. The site was initially identified by Edward Smith of the Glenn A. Black Laboratory of Archaeology, Indiana University, who reported the presence of both surface and subsurface deposits. However, the extent of the subsurface deposits was not known. Because an area immediately adjacent to the known surface site was proposed for a borrow pit, Lutgring Brothers, Inc., agreed to fund a reconnaissance designed to generate data required to delineate the surface and subsurface boundaries of the site.

In addition to a standard systematic surface reconnaissance, 18 backhoe slit trenches were excavated. Dark midden deposits containing FCR, ash, nut and wood charcoal, calcined bone, and chert debitage were identified in nine trenches. On average the midden was encountered at some 45 cm below the modern surface, and in places extended to a depth of 85 cm below surface. Several chert tempered Crab Orchard sherds were recovered from the buried midden which, based on available data, was developed by a single cultural-temporal manifestation. The midden, which extended over an area 150 x 150 meters in size, was avoided by the contractors and remains intact.

The major undertaking was a Phase III excavation at the multicomponent and stratified Bratfish site (12 D 74), located in Dearborn County near the confluence of Laughery Creek and the Ohio River. Phase I and II investigations, also conducted by ISUAL, took place at the site in 1989-90. Data from these studies indicated that a Fort Ancient deposit occurred directly beneath post settlement (historic?) alluvium, and that more deeply buried deposits of indeterminate affiliation occurred in places beneath the Fort Ancient horizon.

The Phase III study was designed to more thoroughly investigate the identified cultural deposits and to examine stratigraphic relationships. Two excavation blocks totalling some 11,500 square meters were sampled through mechanical stripping and hand excavation of units. Utilizing 10.0 cm arbitrary levels, two by two meter units were excavated to various depths, the deeper of which extended to about 3.0 m below the modern surface. These excavations revealed a nearly continuous sequence of occupations at the site, with Fort Ancient, Late Woodland Newtown, early Middle Woodland or Early Woodland, and possible Late Archaic deposits being identified. In addition to materials recovered from unit/level contexts, a total of 37 features were identified and excavated. These included large Fort Ancient refuse pits, a rock filled cooking pit, prepared hearths, fire-cracked rock concentrations, tool caches, and sherd concentrations. No evidence of houses or other structures was found.

Floral, faunal, ceramic, and lithic materials from the site are currently being analyzed. Preliminary results indicate that the most important cultural information from the site will be obtained from the Late Woodland Newtown to Fort Ancient stratigraphic sequence, although significant information regarding site formation processes and valley aggradation was also generated. Data generated might provide insights into the origins and development of early Fort Ancient. A single uncorrected radiocarbon date of 1010 +/- 50 B.P. (Beta-50431) derived from wood charcoal recovered from a Fort Ancient refuse pit was recently obtained. Additional samples from Fort Ancient, Late Woodland, and earlier indeterminate affiliations are being processed.
