A US media report claims that Chamonix is installing snow guns that will colour snow this summer on the Combe de Lachenal in the Flegere ski area, an area prone to avalanches in winter, in a bid to increase safety.

Chamonix is going to be the first major resort to invest in new technology which colours snow as it falls to the ground. The ‘ HiGloSno’ system was trialed last winter at Copper Beach Mountain resort in the US, fires colour capsules in to the atmosphere as snow falls, colouring the snow.
The benefits of the concept includes clear definition of pistes in poor visibility for skiers and boarders, and by colouring snow in different shades for different falls, makes it easier for avalanche, control staff to track different snow layers and project problems.
