Seven recording magnetometers monitored time-varying fields at points on a northwest–southeast line 280 km long in north-central Saskatchewan during July 1981. The experiment was designed to test the hypothesis advanced in 1975 by Alabi, Camfield, and Gough that the electrical conductivity anomaly in the North American Central Plains links with the Wollaston Domain in the exposed Precambrian Shield of Saskatchewan. From clear reversals in the phase of vertical variations, it is evident that the conductor passes between two stations straddling the Rottenstone–La Ronge Magmatic Belt, to the immediate east of the Wollaston Domain. Enhanced horizontal variations transverse to the belt at a third, intermediate, station reinforce this interpretation. Vertical-field response arrows obtained from daytime events in the period range 1–40 min clearly indicate the existence of a major conductor that extends to lower crustal depths beneath the belt. To the northwest across the Cree Lake Zone, reversals in the direction of response arrows at short periods (up to 4 min) imply complex electrical structures in the shallow part of the crust.Lewry termed the Rottenstone–La Ronge Belt a Hudsonian "Cordillera-type" arc massif, and described strong geological evidence for collisional suturing and microplate interaction in this part of the Churchill Province. A similar scenario seems to apply in Wyoming, from the work of Hills and Houston. Thus the conductor appears to trace a Proterozoic plate margin 1500 km from a subduction zone in Wyoming along a transform fault to a subduction zone in northern Saskatchewan.

Disillusionment theory was tested among samples of young, middle-aged and elderly females in a Metropolitan Community on the North Central Plains. This theory suggests that as age increases, so does disillusionment with major American values. The problems of advancing age and poor health, one of the characteristics of the aging experience, are in conflict with the dominant values in American society; a situation which is likely to bring about either a change in values, or expression of disillusionment. Adherence to the work-activity orientation is not likely to decrease since it continues to provide identification and meaning to life. Two hypotheses were substantiated by the data. Religious optimism among women decreases as age increases. The work-activity orientation among women does not decrease by age group. A third hypothesis, that among older women, belief in the mastery of science and technology over nature would decrease, was not supported. The orientation and value change among women according to the data presented is similar to that found for men on the themes of optimism and work-activity, but optimism rather than disillusionment was expressed about science-technology, suggesting the possibility of rural urban and sex differences.
