Surficial Geology

SCALE DESCRIPTION AVAILABILITY and AGENCY
Varies but mostly 1:50,000
Much of the province's surficial geology has been mapped by various agencies such as GSC, MoE, MOTH, EMPR, Agriculture Canada. All available mapping is tabulated in publication entitled "Surficial Geology Map Index of British Columbia" (January, 1992). Available from Crown Publications (OF 1992-13).
Portions of Province
MOTH, EMPR, MoE, BC Hydro MOF


Soils

SCALE DESCRIPTION AVAILABILITY and AGENCY
1:50,000 (digital)
Provide data on parent material, soil drainage, texture, slope, and other related data for near surface soils. Available soils maps tabulated in "Surficial Geology Map Index of British Columbia" (as above), and "Index of Soil Surveys in British Columbia" (1988), by Agriculture Canada. There are some 31 soils maps in digital format.
Portions of province only.
Agriculture Canada, Maps-B.C., MoE


Terrain

SCALE DESCRIPTION AVAILABILITY and AGENCY
1:50,000
Provide information about the distribution and characteristics of surficial materials, landforms, and geologic processes. These maps are not listed in Surficial Geology Map Index of British Columbia.
Portions of province only - see Maps B.C. catalogue
Maps-B.C. as above


Bedrock Geology

SCALE DESCRIPTION AVAILABILITY and AGENCY
1:250,000 (digital)
The GSC are near completion of digitizing exposed bedrock geology mapping for the entire province at 1:250,000 scale; these files will be distributed as Open File works. Index maps showing locations where bedrock mapping has been carried out are available from the GSC. However, these indices are not up to date, and one should also check the information files at the GSC library.
Entire province

Ground Water Maps

SCALE DESCRIPTION AVAILABILITY and AGENCY
Varies
Unpublished ground water maps for Wood Lake area in Okanagan were prepared by the Province. Mapping of Fraser Valley published by NHRI (Halstead 1986). Most maps included in NTS Catalogue maintained by MoE - Ground Water Section. Detailed mapping also done for south Nanaimo area during preparation of water management plan for the Nanaimo/Oyster River area. The Ground Water Section has also prepared Regional Ground Water Potential Maps for east coast of Vancouver Island at 1:20,000 scale. These maps show potential unconsolidated unconfined aquifers, developed unconsolidated aquifers, bedrock aquifers, low permeability unconsolidated deposits, and locations for selected wells with yields in excess of 1 L/s.
