The area was mapped by Kimberley Bailey, in the summer of 2005, with the assistance of Jenna Vanstone. This map was printed from the geologist’s digital file. Geological data were processed using Microsoft Access, and ArcView 9.0 software. Base map was compiled from 1:15 840 scale scanned airphotos supplied by Hudson Bay Mining and Smelting Co. Ltd. Grid coordinates are NAD 83 UTM zone 13 metres east and north. The map was processed overall using ArcView 9.0 software. The map is issued in a package with the Summary of Investigations 2005 Volume 2, Saskatchewan Geological Survey, and is available separately. This map accompanies the following publication: Bailey, K.A. (2005): Bedrock Geology, Myo Rhyolite Distribution Map, Creighton, Saskatchewan (Part of NTS 63K/12); Summary of Investigations 2005 Volume 2, Saskatchewan Geological Survey, Sask. Industry and Resources, Misc. Rep. 2005- 4.2. This map may be referenced as: Bailey, K.A.
