Northwest Territories soil survey enhancement project

8 Aug 2008

This report outlines the methodology used to prepare the digital soil map compilation, discusses the soils and agricultural capability of the study area, and presents project conclusions and recommendations. [...] During the early stages of deglaciation, as the Laurentide ice retreated eastward, but remained close to the Liard and Nahanni Ranges, the confluence of the Liard and Mackenzie rivers was blocked by ice. [...] The most widespread evidence of the former level and extent of Glacial Lake McConnell are the numerous series of sub-parallel beach ridges (Figure 3), most prominent along the regional east-west bedrock escarpment south of the Upper Mackenzie, which extends east of Jean Marie, past the Enterprise area and into the western Slave River Valley. [...] One was in the south half of the Trout Lake basin and the other was east of the Cameron Hills in the southern Hay River valley. [...] In the project study area, the soils of the well to rapidly drained uplands consist of various sub-groups and great groups of the Brunisolic, Luvisolic and Regosolic Orders, developed in alluvial, glaciofluvial, glaciolacustrine and glacial till deposits.
