The great depth of these lakes wouldimply considerable movements of rock, and suchmovements could hardly be of a purely local nature;so it would be expected, if this were their origin,that neighbouring valleys, whose number is legion,would be affected in a like manner and be changedinto lake basins. No slopes have yet been measuredon the terraces that surround Lake Wakatipu, butthose at the upper end of the lake do not appear to.
