ResumoDiscusses the effectiveness of sampling devices demonstrated by summer 1962 field use in northern Yukon and laboratory tests in Mar. 1963. Hand drilling in Yukon Territory produced excellent cores, but the cutting teeth in the ice-corer were quickly dulled from mineral matter; holes 7-8 ft deep required three hrs drilling. Tests with power drives indicated that a two-man team could core a frozen bog 8 ft deep in 30-45 min. The two types of power units tested: a McCulloch chainsaw motor, and a Haynes earth drill, were both adequate; details are given.
