Col du Lac Blanc experimental site is located at the Alpe d'Huez ski resort near Grenoble in the French Alps. Col du Lac Blanc experimental field is located around 2700 m a.s.l and is oriented north–south. The area consists of a large surface of relatively flat terrain (about 25 ha). The pass orientation and the specific configuration of the surrounding summits make the pass closely resemble a natural wind tunnel.The north–south direction accounts for 90% of the wind directions. Aeolian snow transport is observed 10% of the time in winter and occurs with concurrent snowfall 37% of the time It has been dedicated to the study of blowing snow in high mountainous regions for approximately since 1989 by IRSTEA (Snow Avalanche Engineering and Torrent Control Research Unit) and Meteo France (Snow Study Centre).
