Welcome to the Yukon Geological Survey's Integrated Data System (YGSIDS). We are in the process of merging all of our data into one system (see the current state of the conversion process). When this process is complete, the YGSIDS will include all of the Yukon Geological Survey's publicly accessible data.

Abstract

This GIS dataset is a Yukon-wide compilation of surficial geology lines derived from 15 published and unpublished 1:20,000 and 1:25,000 scale surficial geology maps produced by the YGS and City of Whitehorse. Surficial geology line features captured in this compilation include: surficial geological contacts; glacial limits; glacial landforms such as cirques, arêtes, eskers, meltwater channels and moraines; and non-glacial landforms such as faults, lineaments, landslides, and escarpments.

Capsule

The fifteen 1:20,000 and 1:25,000 scale surficial geology maps included in this compilation were either digitized from scanned hard copies or converted from various digital formats where available. See PDF map depicting extent of compilation coverage (pink and orange areas).
 
The original map source for each feature is identified in the “ORIGNL_MAP” field. Eleven of the fifteen maps were originally published by the Yukon Geological Survey for the Anvil Range (105K) area (Bond, 1999). Three additional maps were also published by YGS for the communities of Mayo, Pelly Crossing and Burwash Landing/Destruction Bay (Kennedy, 2011, 2013). One unpublished map is included for the City of Whitehorse (Mougeot, 1997). Where applicable, lines were consistently digitized so that direction-dependent symbology could be applied (e.g. escarpments, meltwater channel arrows, etc).
 
The two key attribute fields within the dataset are “TYPE” and “SUBTYPE” which contain standardized surficial geology line feature terminology. A complete list of standardized surficial geology line features are presented in the following file: “Yukon_surficial_geol_codes.xls” (“LINES” tab). Original feature descriptions are preserved in the “OLD_TYPE” and “OLD_SUBTYPE” fields. Where applicable, the relative age of features is also indicated in the “AGE” field.
 
Please note that because line geometry was captured as reflected on the original maps, line features may not match across adjacent mapsheets published by different authors.
 
These data are a valuable resource for a variety of applications, including: mineral and placer exploration, geotechnical engineering, infrastructure planning, granular resource/aggregate assessments, permafrost modeling, agricultural assessments, forest management and biophysical or ecological land classification.
 
This dataset will be updated as new surficial geology mapping is completed in the territory (e.g. three new maps for the communities of Dawson, Faro and Ross River are expected to be incorporated into this compilation by the end of 2014). Any errors noted by the user of this data should be promptly reported to the Yukon Geological Survey.
