The Aletsch Forest, with its unique population of Swiss stone pine (Pinus cembra), extends around the tongue of the Aletsch Glacier. Low temperatures, piercing winds and long winter seasons limit the growth rate of the trees.
The inhabitants of areas with little precipitation on the south-facing slopes of the Valais have had to cope with aridity for centuries. Through man-made channels called suonen, they divert water from glacial streams to their fields and meadows.
