SOIL SAMPLING AND DRILLING NEAR FAIRBANKS, ALASKA. EQUIPMENT AND PROCEDURES.
Soils explorations were conducted by core drilling methods and by drive sampling methods in thawed and frozen silty soils. Temperatures ranged from 28 to 31.5 F in the permafrost and from 20 to 27 F in the active layer. The Cyclone churn drill, equipped with a field-fabricated 3 in. diameter pipe sa...
