|Abstract||Canadian Geoscience Map 120 depicts the surficial geology and landforms over some 790 km2 covered by the Maxhamish Lake map sheet (NTS 94-O/14) in northeastern British Columbia. In the map area, the
western limit of the Liard Plateau terminates along the north-trending Maxhamish Escarpment. West of Maxhamish Lake, Itssi Creek and tributaries to Sandy Creek drain west into the Liard River, d'Easum Creek flows northeast into the Petitot River.
Maxhamish Lake occupies a centrally located basin with a small catchment area and an outlet draining into d'Easum Creek. Bedrock is mantled by unconsolidated earth materials dating to the Late Pleistocene (Late Wisconsinan Glaciation, > 25 ka to ca.
10 ka) and non-glacial Holocene (ca. 10 ka to present). Deposits of till, green on the map, are generally suitable for placement of infrastructure. Glaciofluvial deposits with mineral, aggregate, and groundwater potential are coloured orange. Slopes
disturbed by landslides, debris flows, and rock falls appear brown and pink. Glaciolacustrine and organic deposits with sporadically discontinuous permafrost are coloured purple and grey. Alluvial deposits prone to flooding, erosion, and
sedimentation appear yellow on the map.|
|Summary||(Plain Language Summary, not published)|
As natural resource development expands in northeastern British Columbia, up-to-date geological information will be needed to reduce the economic costs
and environmental risks of developing new sources of energy and minerals. Canadian Geoscience Map 120 was produced as part of the Geo-Mapping for Energy and Minerals Yukon Basins Project to help meet this demand. The map, legend and accompanying
notes incorporate past research with field observations and interpretation of satellite images to provide new insights into distribution, nature, origin and resource potential of earth surface materials and geological hazards on the Maxhamish Lake
map sheet (NTS 94O-014). CGM 120 is intended for use by governments, universities, resource companies, environmental consultants, First Nations communities, municipalities and the general public.
