19th century military site, Fort Riley, Kansas
The Army City site is an historic 19th and early 20th century military site located on Fort Riley in central Kansas. An electrical resistivity survey was conducted over 22 hectares of the site. The figure shows details of architectural features in a 1.4 hectare subset of the geophysical data. An RM 15 resistance meter was used at a sample density of two readings per square meter and a probe spacing of 0.5 meters. A non-linear high pass filter was used to eliminate resistance variations associated with the geologic "background". Numerous historic features and site patterning are clearly visible.
