Abstract
Some r esults of the final summer's fieldwork on this project re outlined as they pertain to the following topics:
(l) sedimentary structures and paleoenvironment of the
Odjick elastic shelf; (2) paleogeographic zonation of the
Rocknest shelf-edge reef complex; (3) nature and origin of
Rocknest shelf cycles; (4) correlation of the Rocknest
dolomite eastward across Rockinghorse Arch into Kilohigok
Basin and implications of a revised correlation of formations in the Epworth and Goulburn groups; (5) regional variation in low grade metamorphism and its relation to deformation events; (6) basement-involved folding without thrusting in the Tree River belt; and (7) development of "shingle" structures (crudely hexagonal crustal blocks) by progressive conjugate transcurrent faulting.

We were fortunate in having an outstandingly able and
dedicated group of student assistants who regularly
undertook independent geological mapping. It included M. E.
Grier (Queen's), C.A. Gittins (Toronto). M.D. Dayneka
(Memorial). Bradford Johnson (Santa Barbara) and Mark Cunnane (Missoula). The last two are particularly commended for their unstinting efforts without remuneration. For 300 hours of helicopter service without a hitch we thank Edgeworth llelicopters of Fort Nelson, B.C. and pilot-engineer Keith Westfall. Janien Schwarz reaffirmed Napoleon's dictum that an army marches on its stomach, while Win Bowler and Martin Irving provided logistic support at Yellowknife. We were delighted to host M.J. Jackson (BMR, Canberrra. Australia) for half the summer. and briefer visits by D.R. Gray (Virginia Tech) and
R.A. Price (GSC) provided valuable insights. J.P.G. is
