The Fifield Site (Pr-55) is located on Damon Run Creek in Porter County, north-western Indiana. It is classified as a late prehistoric, single-component Upper Mississippian Fisher village.

Initial excavations were conducted by Robert Skinner in 1949. Follow-up excavations were undertaken by Robert Reichert from 1950 through 1959. Charles Faulkner examined collections from these excavations and performed an analysis which was published in 1972.

The excavations yielded features, Prehistoric artefacts, animal bone, and plant remains.

Approximately 45 features were encountered during excavations. Most were reported as basin-shaped, storage-refuse pits. There were 8 features showing firing in the bottom that were interpreted as roasting pits.

Several post moulds were uncovered during the Reichert excavations. No house patterns were discerned but Reichert felt that the patterns of post molds indicated structures with rounded walls.

Approximately 2,713 animal bones were recovered. The most common types of animal remains were deer, dog, elk, beaver, raccoon, bear, bison and turkey. These bones were not modified into tools like the bone tools described in the Artifacts section below, and may be considered food remains.
