| Abstract | The surficial geology represented in this map has been prepared at 1:50 000 scale and published at 1:100 000 scale. Surficial glacial deposits occupy approximately 95% of the map area. The other 5% of
the map area is covered by exposed bedrock represented mainly by Devonian shale, limestone, sandstone, and minor Ordovician and Silurian dolomite, and Cretaceous sandstone and shale. Till deposits (units Tb, Tv, Tp, Td, Tr, Tm and Tx) represent ~ 60%
of the surficial deposits. Lacustrine (units Lp, Lb, Lv, Lm, Lx) sediments represent ~12% of the surficial cover. About 13% of the area is covered by colluvial deposits (units Cv, Cx) most of which constitute landslides (unit Cz). Glaciofluvial
sediments (units Gt, Gp, Gd, Gf and Gx) form about 5% of the surficial deposits and include prominent terraces along the Redstone and Dahadinni rivers. Alluvial deposits (units Ap, A f, Ax) cover about 3% of the map area. Peat deposits cover ~2%.

| Summary | (Plain Language Summary, not published)
Dahadinni River map area (95-N/NW) is a terrain located along the foothills of the Mackenzie Mountains, Northwest Territories and part of the Southern
Mackenzie Corridor. The present map is a surficial geology map published at 1:100 000 scale. The surficial material/sediments mostly represent glacial deposits associated with the Laurentide glaciation in northwest Canada as well as montane and
Cordilleran glaciations during the Late Pleistocene. |
