GRAVEL PROSPECTING BY USE OF AERIAL PHOTOGRAPHIC INTERPRETATION

GEOLOGY, AERIAL PHOTOGRAPHIC INTERPRETATION, AND GEOPHYSICS ARE DESCRIBED AS A RESEARCH UNIT FOR THE RECONNAISSANCE AND EXPLORATION OF SAND AND GRAVEL DEPOSITS SITUATED IN AN ECONOMICALLY IMPORTANT LOCATION TO THE INTERSTATE HIGHWAY SYSTEM IN NORTH DAKOTA. THIS RESEARCH HAS BECOME NECESSARY DUE TO A RAPIDLY DIMINISHING AGGREGATE SUPPLY COMPARED WITH A GREATLY INCREASED HIGHWAY CONSTRUCTION PROGRAM. THE PROCEDURE IS PRESENTED FOR GRAVEL SEARCH IN A LIMITED CRITICAL AREA. AVAILABLE PUBLISHED GEOLOGIC LITERATURE IS STUDIED AND THEN A COMPLETE COVERAGE PROVIDED BY AERIAL PHOTOS. AFTER ARRIVING AT THE FIELD OF LOCATION DESIGNATED ON THE AERIAL PHOTOGRAPH, A SMALL MOBILE DRILLING UNIT IS POSITIONED AND A TEST BORING MADE. OTHER PROBES ARE MADE TO ESTABLISH THE LOCATION AND THE APPROXIMATE AVERAGE THICKNESS OF THE DEPOSIT OVER THE AREA. AT PRESENT, IT IS THE POLICY TO TEST AND DETERMINE THE QUALITY AND QUANTITY OF A SAND AND GRAVEL SOURCE USING A LARGE POWER DRIVEN HYDRAULIC AUGER, BUT FUTURE PLANS CALL FOR USE OF EARTH RESISTIVITY EQUIPMENT TO ASSIST IN THE FIELD EXPLORATION.
