Blackadar and Murphy returned to Cape Dorset on
September 18 and left on September 23 aboard the C.G.S.
C.D. Howe,reaching Quebec on September 30. It is expected
that mapping will be continued in the Amadjuak area in 1959.
Southeast District of Mackenzie. A reconnaissance
survey of an L-shaped area in southeast District of Mackenzie,
0
between latitudes 60 0 and 62 north and extending from Nonacho
Lake in the west to Wholdaia Lake in the east, was carried out by
F.5:. Taylor thus completing mapping in this part of the Precambrian
Shield except for a small area west of Wholdaia Lake. A party of
ten was in the field from the first week in June, when ice covered
all the larger lakes, until the first week in September. Canoe
parties, consisting of two men. were supplied from Uranium City
by Otter aircraft. Glacial deposits, such as eskers, drumlinoid
ridges, and morainal ridges, cover much of the area. In these
parts a float-equipped Cessna 180 aircraft was used for a period
of three weeks and proved valuable in moving ground parties and
in making spot observations.
The area lies athwart the tree-line and small black spruce
trees are dominant. Game is scarce except during the caribou
migration. Lake trout is common in the lakes and most streams
contain grayling.
Western District 9..f Mackenzie. :!..~ Jeletzky continued
the study of the stratigraphy and palaeontology of the Cretaceous and
uppermost Jurassic strata southwest of the Mackenzie River delta
initiated in 1955. Field work was carried out on the eastern flank
of the Richardson Mountains between the latitudes of Alclavik and
Fort McPherson. A few days were also spent on parts of the
Porcupine River in the Yukon. J.V. Ross and R.D. Lawrence,
seasonal employees, completed detailed mapping in the Mesa Lake
and Rodriques Lake map-areas north of Great Slave Lake.
I
Northern Ellesmere Island. R.L. Christie made
reconnaissance studies in the Lake Hazen region of northern
Ellesmere Island and was attached to the Defence Research Boardls
"Operation Hazen" for administrative and logistical purposes. This
work had been started in 1957 and was continued this year with the
assistance of~•..!:. Walker.
Field work began on May 4 with a flight to Ward Hunt
Island by Dakota aircraft. The valleys tributary to Disraeli Bay
