Edgewater Park Site

The Edgewater Park Site is a 3,800-year-old Late Archaic campsite situated along the Iowa River in Coralville, Iowa, United States.

Excavations revealed a small encampment of two hearths and areas for faunal and stone tool production.

Lithic analysis reveals that the site occupants probably recently traveled along the Iowa River from the north center of the state and were engaged in late-stage tool manufacture and maintenance.

Floral analysis indicates the site occupation occurred during the warm half of the year and that the occupants utilized little barley, a non-local plant which was later cultivated, and barnyard grass, a local plant probably also later cultivated.

This site is interpreted as a short-term, late warm-season occupation of people migrating down the Iowa River, possibly towards winter encampments in what is now the southeast part of the state.
