Frosty pane

It’s -21F (-29C) and the temperature is still dropping. My kitchen window is completely covered with “fern feathers”.  The ice crystals have grown from single stalks to full fledged sheets of ice as the temperature outside the window drops.

Initial formation of crystals enlarges quickly in the intense cold.

The ice crystals sort of resemble palm fronds that have fallen to the ground.

lake crystals

We don’t often get the weather conditions on our local metropolitan lakes that result in spectacular ice formations, like those seen on Lake Superior.  You can view some great examples of those formations on Paul Sundberg’s photography website.

But high winds and freezing temperatures did produce some very nice lake crystals on Lake Vadnais yesterday morning, as the spray from waves hitting the shoreline vegetation coated every twig with ice.

Gusty winds channeled the waves into a small bay on Lake Vadnais in St. Paul.

They almost look like the icicle-shaped crystals you see on an expensive chandelier.

Spray from the wind-driven waves was still adding to the ice formations, even at 11 a.m.
