These investigation generated several publications, reports,
maps, with comprehensive presentation of tectonic, strat jgraphy,
and geological evolution of the area (Douglas, 1970, Norris,
1972,1973,1975,Norris et al.,1963, Lenart,1973, Hawkings and
Hartleilid, 1975, Yorath and Norris, 1975, Young et.al., 1976)
Also surficial geology is known better as many new data has
been generated in 70's by the mapping programs associated
with the inventory and assesment of natural resources for
the Mackenzie Transportation Corridor, (Hughes et al.,1973,
Rutter,1977)
Presented area is tectonicallv very complicated and
displays diversity of elements. The main tectonic
elements are: Beaufort-Mackenzie Basin, Cordillera Orogen and
to the east Northern Interior Platform. Each of these elements
has own individual style and history of evolution, freauently
with multiple epizodes of deformation, ea. Collumbian (Mezozoic),
and Laramide (Late Cretaceous and Tertiary),(Young et al.,1976)
Using morphostructural and morphosculntural criteria of
geomornhologic mapping and techniaue of Landsat data interore-
tation, the following morphological units have been identified:
Ae Subaerial relief
I.Destructive relief on epigeosynclinal Cordillera Orogen
1.British Mountains
2 .Barn Range Mountains
3.Richardson Mountains
II.Accumalative-denudational relief of Cordillera on shallow
seated base
4.Ammerman Hills
5.Barn Ridges
GeDriftwood Hills
b.Intermontane _depressions
7.Timber Creek Basin
8.Muskeg Basin
9.Babbage River Basin
10.Blow River Basin
ll.Driftwood Basin
12.01d Crow Basin
13.01d Crow Flats
IV.Accumulative-denudational relief of Arctic Continental Slope
14.Yukon Coastal Plain
15.Arctic Plateau
16.Mackenzie Delta
Listed above morphological units are characterized by
complexes of morphometrical, morphostructural and morphody-
namic indices, partialy detectable on Landsat mosaics.
Old Crow Flats, for example, represent central part of
Old Crow Basin, with nonmarine Tertiary to Recent sediments from
500 tO 700 m thick.(Lawrence,1973)Flats are spotted with
