Some thirty test holes were drilled at a location on the Highwood River to determine its suitability as a potential dam site. In most cases the alluvium was cased, and cores taken from the underlying bedrock; enough core was available to provide a composite section more than 400 feet thick. The described section includes strata of the Mississippian Mount Head and Livingstone Formations.
