Wow.  Ever seen an ice storm?

This took place in Lake Léman (also known as Lake Geneva), Switzerland, in January 2005.

One news account, for example, reported that:

The cold did not save sailing ships moored in the ports of Léman. In
Geneva, several boats sank under the weight of the ice. Several minor
roads were closed, passage having been made impossible by the ice and
the snowdrifts. In downtown Geneva, Servette Street was closed after
the rupture of a water pipeline transformed the roadway into a true
skating rink.
