Three northeasterly faults, from north to south the Granduc, the Central, and the Scotty Dog, cross Leduc Valley transverse to the normal Cordilleran trend a few miles east of the Coast Range bath olithin northern British Columbia. Earlier steep isoclinal folds trend northwest and are flexed dextrally upward on the northwest side of the Granduc fault and crumpled and cross-folded between Granduc and Central faults. Between Central and Scotty Dog faults east-striking semirecumbent folds have been overturned southward and drag-folded eastward. Directly south of Scotty Dog fault the structural trend is N. 65° E. This trend apparently persists under ice-covered areas for several miles southward and was first noted by Buddington in 1925 near Hyder, Alaska.
