New geochemical data from re-analysis of archived stream sediment samples have been assessed using weighted sums modeling and catchment basin analysis as described in the methodology report that accompanies this map (YGS Open File 2015-10). Both commodity and pathfinder element abundances are evaluated to highlight areas that show geochemical responses consistent with a variety of base and precious-metal mineral deposit types. The results of modeling, completed using two approaches, are presented as a series of catchment maps and associated data files. This release is part of a regional assessment of stream sediment geochemistry that covers a large part of Yukon.

Unincorporated areas can have Advisory or Hamlet Councils that carry out an advisory role for the Local Advisory Area and is the community voice in the process of developing plans.

This GIS dataset is a Yukon-wide compilation of surficial geology points derived from 75 published and unpublished 1:50,000 surficial geology maps produced by the GSC, YGS and various universities. Point features captured include: field station, fossil and sample locations; glacial landforms such as erratics, kames, kettles, drumlins and flutings; permafrost features such as pingos, palsas, patterned ground and thermokarst depressions; and other non-glacial landforms such as landslides and tors.

Landscape hazard maps were completed as part of a community hazards mapping program coordinated by the Northern Climate ExChange (Yukon Research Centre, Yukon College). Potential landscape hazards were assessed under changing future conditions by incorporating a variety of data sets, including surficial geology, topography (slope and aspect), permafrost distribution, site-specific permafrost data (e.g. ground penetrating radar, electrical resistivity tomography and borehole data), analyses of past hydrological and climatological trends, and future climate projections. The landscape hazard map identifies existing and potential geological hazards such as landslides, permafrost stability and flooding. The hazard map is presented in stoplight colours to provide an intuitive tool for community decision makers aiming to incorporate an adaptation planning framework into existing land use management practices. Detailed descriptions of data inputs and hazard analysis methodology are presented in an accompanying report (available for download from http://data.geology.gov.yk.ca/Reference/DownloadProduct/49696). An accompanying surficial geological map also describes detailed landscape characteristics such as surface landscape features, sediment texture, genetic material, surface expression and geomorphological processes (available for download from http://data.geology.gov.yk.ca/Reference/DownloadProduct/49697).

This CD-ROM contains digital data files that were assembled or created from the 2002 Glenlyon component of the Targeted Geoscience Initiative (TGI) project. All data is provided in formats easily explored using widely available free softwares, which are distributed on this CD. Features of the CD include GIS spatial data of bedrock and surficial geology, generalized background topography and georeferenced geophysical and satellite raster images. Interactive map projects to allow viewing and querying of the spatial data using a variety of common GIS software (ArcExplorer 2.0, ArcView 3.x, ArcMap 8.x, and MapInfo) Databases of field observations (bedrock and surficial geology) Publications relevant to the study area, including open file maps, and a collection of reports from the Yukon Exploration and Geology (YEG) series A photo gallery to illustrate representative rock units and surficial geology features Free softwares (Adobe Acrobat Reader 5 and ESRI ArcExplorer 2) for viewing publications and interactive maps. Navigation to the features described above is through a user-friendly interface which launches upon loading of the CD. All features can also be accessed through Microsoft Explorer.

This high sensitivity aeromagnetic survey was carried out by Goldak Airborne Surveys (Goldak) on behalf of the Geological Survey of Canada (GSC) between January 25th and March 26th, 2011. Aircraft equipment operated included three cesium vapour magnetometers, a GPS real-time and post-corrected differential positioning system, a flight path recovery camera, VHS titling and recording system, as well as radar and barometric altimeters. All data were recorded digitally in GEDAS binary file format. Reference ground equipment included two GEM Systems GSM-19W Overhauser magnetometers and a Novatel 12 channel GPS base station which was set up at the base of operations for differential post-flight corrections. Eighty two flights (including test and calibration sorties) were required to complete the survey block. A total of 37,999 line kilometres of high resolution magnetic data were collected, processed and plotted. The traverse lines were flown at a spacing of 400 metres with control lines flown at a separation of 2400 metres. Nominal terrain clearance was specified at 100 metres above ground.
