| Abstract | The Enterprise map area is a low-relief terrain bisected by a prominent Devonian carbonate bedrock escarpment. Ice-flow indicators show a clockwise shift in Laurentide Ice Sheet flow from southwest
(230°), to west (280°), to northwest (305°). A late-stage southwestward surge from the Great Slave Lake basin is also preserved as drumlinoid ridges below the escarpment. During deglaciation, ice retreat impounded northeastern drainage forming local
ice-contact lakes and areas of subaerial glaciofluvial outwash. As ice continued to retreat, the northern portion of the map area became inundated by glacial Lake McConnell, within which the Snake Creek Moraine and associated subaqueous fans formed.
Prominent flights of beach ridges record the drainage of this lake. Exposed nearshore and littoral lake sediments were subsequently remobilized into eolian dunes. Bogs and fens have formed over much of the low relief landscape and display extensive
thermokarst. |
| Summary | (Plain Language Summary, not published)
Surficial geology map of the region around the community of Enterprise, which includes part of NWT Highway #1 on this sheet, and other minor existing
infrastructure. This map will provide detailed information on the surficial materials that were deposited in the region, which can be used for information planning, mineral exploration and future climate change scientific studies (e.g.,
permafrost). |
