| Abstract | The northeastern Cameron Hills comprise a Cretaceous bedrock upland, rising >550 m above the regional boreal plains. It was inundated by the Laurentide Ice Sheet and includes much of a prominent 60 by
20 km southwest-oriented mega-scale glacial lineation field, formed in thick till. Subsequent ice flow on northeast Cameron Hills occurred north to south, and a series of lobate and ice-thrust moraines suggest glacial surging. Rotational bedrock
slumps cover the eastern and northern flanks of Cameron Hills, and extensive alluvial fan deposits draining from these slopes blanket the surrounding topography. The Cameron River formed as a glacial spillway, draining southwest across the upland
before turning north and draining into Tathlina Lake. An expansive raised delta and glaciolacustrine sediment cover extending up to ~295 m above sea level, south of Tathlina Lake, records impoundment of an ice-marginal lake between the
northeastward-retreating Laurentide Ice Sheet and Cameron Hills. |
| Summary | (Plain Language Summary, not published)
This map presents the surficial geology reconstruction for the area of the Cameron Hills and surrounding Hay River and Tathlina Lake lowlands in southern
Northwest Territories based on extensive ground truthing, till sample collection and air photograph interpretation. It depicts multiple phases of ice flow, including those preserved in conspicuous and in places cross-cutting mega-scale glacial
lineations (MSGLs) and glacial fluting fields, and a sequence of declining shorelines and related deposits related to the formation of deglacial lakes from a high point of ~290m above sea level. The map also identifies extensive areas of thermokarst
(melting of ice-rich permafrost) in widespread areas of bog and fen deposits. This map provides a basis for comprehending regional glacial sediment dispersal as it applies to studies of mineral dispersal and exploration. |
