Walking in the snowy landscape of Axalp, high above Lake Brienz in the Swiss Bernese Oberland.
A pedestrian-only footpath through the woods and cliffs on the southern shore of Lake Brienz.
When the temperature of snow is above -10°C, it melts slightly when you crush it by walking on it. At temperatures below -10°C, the ice crystals are crushed, which makes a squeaking sound.
A spring-like day and an afternoon stroll around a little village on the shore of Lake Brienz.
