Abstract

In reply to Lovejoy's discussion (ibid., p. 153-157), Christensen notes that evidence for the age of faulting at McGee Mountain is not conclusive. He considers Lovejoy's comments on thesignificance of the basalts as a valuable contribution to the problem, and concludes: '(1) A low escarpment, less than 1,000 feet existed when the basalts were erupted on McGee Mountain. (2) McGee glaciation occurred before any significant cutting of McGee Canyon, possibly contemporaneously with the basalts. (3) The oldest probable age for the major part of the relief, about 3,000 feet, on the escarpment is the age of the McGee glaciation. (4) The escarpment existed as it does today before the Wisconsin glaciations.'
