He spent five summers as a meteorological and glaciological observer, first at Knob Lake
and then on northern Ellesmere Island, where he was a member of Operation Hazen, the research expedition led by Geoff Hattersley-Smith.
As Martin (1959) has recently deduced, the tree size suggests a taiga or open forest type of association, such as is now found at Knob Lake near 54[degrees] North Lat.
Nevertheless, in comparable forest environment at Knob Lake, mean annual precipitation is only 32 in.

The McGill Sub-Arctic Research Laboratory opened in 1954, when the railroad from the new port of Sept Iles reached Knob Lake (later Schefferville), Quebec, to open up the massive iron mines of that region.
Data from these projects were reported regularly as an adjunct to the Knob Lake A weather station reports.
There he earned his Master of Science degree with Bill Weber by working up plant collections he had made at the Knob Lake
subarctic field station of McGill University, Schefferville, Quebec, followed by a doctorate with John Marr on primary succession on the Muldrow Glacier foreland, Denali National Park.
Although Harper's travels in Ungava took him to several locations between 53 [degrees] and 57 [degrees] N, he conducted most of his fieldwork within 20 km of Knob Lake, near the Quebec/Labrador border, at 54 [degrees] 50'N.
In my opinion, the major value of Harper's work lies in the wealth of natural history observations contained in his major papers, especially those focused on a single locality such as Windy River or Knob Lake.
