There are close geometrical and dimensional similarities between the faults in Scotland north of the Highland Boundary Fault and faults in southern California east of the San Andreas Fault. It is argued that the Moine Thrust and Oarlock Fault are equivalents and that the Great Glen Fault and the Rosamund Lineament are also equivalent, implying corresponding senses of movement and that the Highland Boundary Fault originated as a dextral transform. The comparison cannot be extended yet to the terrains to the N of the Oarlock Fault or W of the San Andreas or to the corresponding areas in the Caledonides.
