Survey Description


In 1985, 295 samples were collected to obtain representative coverage of the study area.  At each site, approximately 10 litres of diamicton from the C-horizon was sampled from hand-excavated pits at 1.5 to 3 km intervals along roads accessible by 2-wheel drive vehicles.  During the summer of 1986, 82 samples were collected in a 36 km2 area which encloses the mouth of the Assemetquagan River.  Approximately 25 litres of material was screened on site to -4 mesh (<4.75 mm).  Care was taken to collect samples in the C-horizon, however, most sites lacked distinct soil horizons.  Sixty-nine samples were collected on the upland surface at a spacing of 500 to 700 m.  Thirteen more samples were collected on the valley slopes within the lower 1 km segment of the Assemetquagan River, for a total of 82.  The data are published in Geological Survey of Canada Open File 1586.
