Site name: Wuamett Farmstead
Type of survey: Resistivity; Instrument: Geoscan Research RM-15; Prospection depth: 0.5 m; Sampling interval: 0.5 x 0.5 m; Area surveyed: 3,330 m2; Date of survey: 10/98.
Comments: The John O. Wuamett farmstead, established
in 1856, is an early pioneering settlement in Steele County.
It has been continuously occupied by the Wuamett family until
recently. The original farmhouse may be incorporated within
the structure currently occupying the site (above). Exploratory
geophysics was conducted as part of BRW's Minnesota Farmstead
Study with a goal of locating privies, other subsurface features,
and structures. In the electrical resistance results (left),
many of the large trees and bushes on site yield circular zones
of high resistance (black). This survey located
several anomalies in the vicinity of a known privy that suggest
the presence of multiple additional privies (the magnetic
gradiometry data support these findings). The resistance data
also yield tantalizing suggestions of possible buried structures.
Type of survey: Magnetic gradiometry; Instrument: Geoscan Research FM-36 fluxgate gradiometer; Prospection depth: up to 1.5 m; Sampling interval: 0.25 x 0.5 m; Area surveyed: 4,000 m2; Date of survey: 10/98.
Comments: With an occupation to contemporary times, this
farmyard is loaded with historic and recent iron and steel artifacts
and debris that greatly impacted the magnetic survey. Foremost among
these were well pipes, a septic tank, water pipes,
and various utility lines.
Nevertheless, the magnetic data supported several of the more subtle
findings indicated by the resistance survey.
