The purpose of this thesis was to study the geomagnetic variation anomaly at Kootenay Lake, B.C., first reported by Hyndman in 1963. The anomaly is characterized by a very high correlation between the vertical and horizontal north-south geomagnetic components; this indicates anomalous currents striking magnetic east-west, to the south of Kootenay Lake.
During the summer of 1968, twenty recording stations were set up in the Kootenay Lake area, using four Askania variographs and three fluxgate magnetometers. Spectral analysis shows that the main 'low I - high I' discontinuity was traversed over a relatively short distance on a north-south profile, to the south of Kootenay Lake. Polarization studies indicate anomalous currents striking magnetic east-west in the same general area of the above discontinuity.
The model proposed is a localized distortion of the main 'low I - high I’ discontinuity, resulting in a well defined conductivity step, striking magnetic east-west, to the south of Kootenay Lake. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
