Catalogue Number 2002-4.2-(2.3 )
Project M.138 of 2002 The area was mapped by Ralf O. Maxeiner and Rebecca Hunter, in the summer of 2002, with the assistance of Shawna Leatherdale, Vance Hachkewich, and Jason Craven.
a were processed using Pendragon Forms, Microsoft Access, and ArcView 3.2 software. Base maps were compiled from 1:50 000 scale digital topographic maps licensed from Saskatchewan Information Services Corporation. UTM coordinates are NAD83 zone 13. The map was processed overall using ArcView 8.2 software. The map is issued in a package with the Summary of Investigations 2002 Volume 2, Saskatchewan Geological Survey, and is available separately.
