These data points are sites visited by Dr. Jozsef Toth during his 1964 to 1969 fieldwork. Dr. Toth is a distinguished hydrogeologist who developed and published his landmark 'Unit Basin' theory of steady state flow leading to the fundamental concept in hydrogeology known as 'Tothian flow system theory'. His contributions to hydrogeology turned the Research Council of Alberta, and subsequently the University of Alberta, into internationally renowned institutions for hydrogeological research. All datapoints relate to the sites in Alberta Geological Survey report INF 143. Field parameters (Temperature, Electrical Conductivity, and Flow Volumes) measured or estimated were retained as attributes to the point data. The data are in ESRI shapefile format.
