Survey Description

During the summers of 2004 and 2005, helicopter-supported stream sediment and water sampling were carried out at 655 sites in the Old Crow area of northwest Yukon Territory.

The data are published in Geological Survey of Canada Open File 5319/Yukon Geological Survey Open File 2006-17.

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

Sampling Procedure

NGR stream sediment and water

At each site a pre-labelled Kraft paper bag was two-thirds filled with silt or fine sand collected from the active stream channel.  In practice, the silt sample was collected after water samples were collected but before a bulk sediment sample.  Handfuls of silt from various points in the active stream channel were collected while gradually moving upstream.  A moss mat sample was sometimes collected when a suitable sample was scarce or absent.

At every site, waters were sampled mid-channel, from flowing water where possible.  At sites where sediments were taken for heavy mineral concentration (approximately every second site) two water samples were generally collected.  Samples were collected in 125 mL Nalgene bottles.  The bottles were rinsed two or three times before collecting the sample.

The geographic extent of the survey is defined by the following polygons:

  • Covers parts of NTS 116 J (Porcupine River), K (part of Porcupine River), N (part of Old Crow), O (Old Crow) and 117B (Davidson Mountains) in the Old Crow area, northern Yukon Territory.  The community of Old Crow (located 550 km northwest of Whitehorse) is located in the eastern part of the study area.  It is bounded to the southeast by Fishing Branch Ni’iinlii’njik Park.

  • Covers parts of NTS 116 O (Old Crow), P (Bell River), and 117A (Blow River) northern Yukon Territory.  It is located approximately 70 km northwest of the community of Old Crow.
