The snowpack is melted away except in the high alpine, and summer mountaineering season is here. Get up early and take advantage of an alpine start to make the most of a cold morning before the snow turns wet in the afternoons.

The summer snowpack exists in high alpine (above 3000m) and on glaciated areas, and consists mainly of well settled summer snow with the occasional dump of fresh snow and windslabs following a storm. Look for a solid overnight freeze for the best conditions, and avoid steep slopes when they're baking in the sun or soaked with rain.

During the first half of the summer, the high mountains are still shedding their winter snowpack and wet avalanches and cornice failures can be expected during the afternoons. Following a summer snowstorm, windslabs can also be expected during the immediate 24-48 hours following the storm.
