LAC DE COURVAL STRUCTURE

LAC DE COURVAL STRUCTURE

  • Type: Simple
  • Location: N 48° 50.1’ W 78° 59.8’
  • Diameter: ~1.6 Km
Lac de Courval, Quebec, Canada

An article by Beals et al in the 1964 Journal of the RASC article (below) proposed that Lac de Courval may be the result of a cosmic impact. This report was published before any geological studies were performed at the site in order to find impact features.

 A later magnetic survey to find impact related geology was NEGATIVE. I have not found any reports describing the surveys performed at this site.

In conclusion, a remote possibility exists that this structure is impact related.
