Continuation of the Great Glen Fault Beyond the Moray Firth

DURING 1944–45 I was stationed in Fair Isle, Shetland, during which time I was able to make anumber of general observations on the geology of the island which tend to support Dr. Flinn's hypothesis¹ that the Great Glen Fault continues northwards, past the west coast of Fair Isle, to Shetland, where it is called the Walls Boundary Fault. Because of the inaccessibility of the Isle and its important position relative to the suggested course of the fault, it is worth while recording the observations; but it must be emphasized that they are recollections, supported by only a few photographs, specimensand notebook data.
