I have setbacks, but I keep myself together

Lac Blanc was formed by the melting waters of the Gébroulaz glacier. It is interesting to note that in the eighteenth century, in the midst of the Little Ice Age, Lac Blanc did not yet exist and the Gebroulaz glacier had a larger surface. The water leaves the lake by a “leak” close to the banks. The water system becomes temporarily subterranean in the limestone rock, then reappears further downstream by a resurgence.
