Garden Coulee (32WI119)
19th Century Hidatsa Settlement, North Dakota
The Garden Coulee Site is the location of a village occupied by the Crow-Flies-High band of Hidatsa in the mid 1800s, near the site of the then-abandoned Fort Union trading post. Archaeo-Physics surveyed the site in November 2002, as a part of a multi-disciplinary investigation performed by the Midwest Archaeological Center, National Park Service.
The image above is a detail from a larger (roughly 6 hectare) survey area.The image map displays electrical resistance data; the colored contours represent magnetic field gradient data. A number of large, high-amplitude magnetic anomalies are associated with distinct highs in the resistance data. Previous research at the site suggests that these are due to large storage/refuse pit features, although they are also consistent with hearth features. The linear low-resistance feature in the southwest corner of the data plot is caused by a modern road.
The Geophysical survey results are treated in greater depth on the Midwest Archaeological Centers Garden Coulee website, along with the history of the Crow-Flies-High Band and the archaeology of the Garden Coulee Site.
