Project Name: The Garden Coulee Site
Reference: http://www.cr.nps.gov/mwac/fous/garden_coulee/geo_invest.htm
Geophysical Investigations of the Garden Coulee Site were initiated in the
summer field season of 2001. Midwest Archaeological Center (MWAC) Contracted
Archaeophysics LLC to perform the surveys using Geoscan Research Resistance
and Magnetic Instruments. A Geoscan Research FM36 Fluxgate Gradiometer was used
to collect the the magnetic field gradient data where 4 samples were taken per
meter every .5 meters. Later grids were surveyd with a transect interval of
1 meter, but with no apparent comprimise of data interpratbility. A Geoscan
Research RM15 Resistance Meter with a PA5 probe array was used for the resistance
survey. 2 samples were taken per meter with 1 meter intervals between transects.
The combination of data was to be used along with pedestrian survey data in
addressing questions about site integrity, site limits, and intra-site patterning.
The investigation identified geophysical anomalies interpreted as archaeological
features.
