The number of sites have been doubled  and this     shallow inclination confirmed (new inferred displacement of     $1900 \pm 700$ km).  These results pass the fold     test, with maximum precision at 100% unfolding. The Carmacks    Formation is comprised of fragmental beds overlain by     extensive flows which grade upsection from basalt or     andesite to primitive ankaramites.  The rocks have a     peculiar petrochemical signature (Francis and Johnston.     1996, this volume) which, in combination with the     coincidence of the paleoposition of the Carmacks Formation    and the paleoposition of the Yellowstone Hotspot have led     us to conclude that the Carmacks Formation represents the 70    Ma extrusion of the Yellowstone Hotspot.  This segment of     the hotspot track (and much of the Intermontane Belt) was     subsequently displaced northward, dragged by Kula plate     oblique subduction in the Paleogene.
