Details:  A Jennings River high-resolution aeromagnetic survey (NTS 104O) was completed in 2006. Funding for the survey was provided by Geoscience BC (Project 2005-059) and project management was undertaken by the Geological Survey of Canada. The survey was flown under contract by Goldak Airborne Surveys, Saskatoon. This map, in UTM Zone 9 projection, features 2 magnetic parameters, residual total magnetic field and first vertical derivative of the magnetic field. 

The map also displays geological mapping by Nelson et al., 2001 in the 104O/14E and 15 maps areas (see also Jennings River map in Albers projection).  The files are available for download in various formats.  Details of the aeromagnetic survey can be found in the Fieldwork 2006 article by Miles, W.F., Dumont, R. and Lowe, C.: Aeromagnetic Survey over the Jennings River Map Area, Northern BC (PDF document, 101 Kb).
