Survey Description


Helicopter-supported sample collection was carried out during the summer of 1995 in the Cry Lake map area, British Columbia.  A total of 1228 stream sediment and 1213 stream water samples were collected from 1159 sites.  The average sample site density was 1 site per 12 km2 over the 13,173 square kilometre survey area.  Field duplicate samples were collected in each analytical block of twenty samples.  The data are published in British Columbia Regional Geochemical Survey RGS 44.

This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.

Sampling Procedure

Primary and secondary drainage basins with catchment areas of less than 10 km2 were sampled.  Sediment samples weighing 1 to 2 kg were obtained from the active stream channel.  Samples were primarily fine-grained material mixed with varying amounts of coarse sand, gravel and organic material.  Surface water samples were collected in 250 mL bottles and suspended solids were excluded where possible.
