ADCOH Site Area
The ADCOH (Appalachian UltraDeep COre
Hole) site in northwestern South Carolina
was selected for the purpose of siting an ultradeep (10-11 km) scientific hole.
Part of the site study included the determination of heat flow at four holes
located as shown in the following figure. Details of the heat flow results were
reported by Costain and Decker (1987).

The near surface geothermal gradient at the ADCOH Site in northwestern
South Carolina is about 18-20°C/km. The heat flow is about 55 mW/m2. The
maximum temperature expected at a depth of 10 km is less than 200°C.
