Anyone who extends their ski touring season into early summer is bound to have seen them before. Many of us may know that the strange red spots on the early summer firn are algae (Fig.1 ). But they are by no means the only inhabitants of our treasured snow cover. Snow and glacier ice are much more than a sterile collection of frozen water. They are dynamic ecosystems made up of a multitude of microorganisms that have undergone hundreds of millions of years of evolution to adapt to these harsh environments.

"Nothing can happen in the forest." - This is probably one of the most widespread misconceptions among skiers. It is true that statistically there are fewer avalanche accidents in the forest. However, those who are lulled into a false sense of security are unconsciously taking a high risk and acting carelessly. In today's SnowFlurries we therefore take a look at how the forest influences snowpack stability and what skiers need to bear in mind.
