Icicles

Icicles slowly grow on these old houses. The insulation in the attic spaces isn't the best, so the snow gradually melts, forming water. Of course, that water re-freezes again as soon as its away from the heated roof and the result can be seen here. It gets more dramatic if there's a spell of sunny weather; then the heat from the Sun helps the melting process along, creating icicles as long as 6 feet (1.8M).

Don't walk between the houses until they break off!
