Arctic Butte Northeastern Corner of Saskatchewan 1962-1963 £xped/rions ^ CAMP Sco/e (opprox/more) - - ROUTE ESKER KILOMETERS tl Figure 1. The northeastern corner of Saskatchewan. Sand deposits located south and west of Hasbala Lake are probably attributable to Glacial Lake Kazan, in the southwestern District of Keewatin, which was described by Lee (1959). This Pleistocene Lake was estimated to stand between 1, 253 and 1, 260 feet above sea level and would have innundated much of the area around Hasbala and Patterson Lakes. The strata underlying much of the area is granite which is often red in colour (Tremblay, 1959). Red granite cliffs and a hill composed of red granite were observed west of Patterson Lake. In the region around Hasbala Lake, which Tremblay did not visit, we observed metamorphic cliffs composed of gneisses similar to those described by Tremblay as "fine- to medium-grained, granular, massive to foHated, quartz-feldspar-biotite gneiss". Plant Communities A brief consideration of the vegetation of northeastern Saskatchewan will permit a better understanding of the habitat notes in the annotated catalogue of plant species. The communities described here were recognizable in the field; however, their limits are arbitrary. Vegetational patterns are often obscured by the complex regeneration of plants after fire and habitat intergrada- tion. Some of the following communities were dominant features in the.
