“…The resulting anomaly data were compared with data from 11 smaller surveys covering parts of the quadrangle (Johnson and others, 1965;U.S. Geological Survey, 1966, 1980a, 1980bMudge and others, 1968;Kleinkopf and Mudge, 1972;Douglas, 1973;Hanna, 1978;Lidke and others, 1983;Madson and others, 1983), many of which had been shown (Hassemer and Hanna, 1982) to exhibit inconsistencies relative to one another. This comparison of data sets served to verify the existence and locations of several important anomalies.…”
