Ice Ponderings

These are the last of the ice photos that I’ve selected for the blog.  Now we’re back in the deep freeze with snow on the way for the weekend so we won’t be seeing more clear ice for a while.  A photographer’s opportunities don’t last forever!DSCF7868

Does it seem like there is open water in this picture?  You can tell by those trapped bubbles that there is a thin layer of ice there.  The water is quite deep here and that ice won’t even hold up our six pound Yorkie.  Luckily he seems to understand the danger and sticks to the shore.  DSCF7853

Feathers and bubbles are two of the most noticeable features of this ice.  The feathers are like dragonfly wings trapped in amber.  The bubbles are like stars in a black sky.DSCF7874

Bigger bubbles, frozen at the surface.  See that pile of shapes above the rock on the far right?  The air was moving away from the rock, under the top layer of ice, and it froze in six stages.  It made chambers as it grew, like a baculite does, only these icy sutures are smooth and random.DSCF7871

A mix of patterns in ice and air, trapped in place as the water swirled around the tree trunks.  Forest debris fell or was blown in even as the ice froze.DSCF7864

Spindles and feathers: what makes them grow?  Are these the beginnings of the spikes and triangles seen in other pictures?DSCF7861The spindles have frozen sweat, condensed droplets frozen separately against the top layer of ice, along their chilly spines.

Macro-Ice

Here are more pictures of the ice formations that grew this week after a warm spell. Everywhere were different patterns and shapes, thicknesses of ice, types of crystals and transparency of the ice depending on whether the water had been moving or still, in the afternoon sun or shade, or littered with forest debris when it froze. Come by tomorrow to see more 🙂

It would take some study to figure out exactly what happens in each case.  My guess here is that the bubbles formed before the surrounding ice froze, then froze themselves.  The blue shadows are intense against the transparent ice.

Why do the triangular crystals rise above depressions?  Why do they grow in triangles, with holes in the middle?

Here you can see the clarity of the ice, but also bubbles, fingerprint-like growth lines, frosty edges and the curious, matte freckles.DSCF7850

This pattern reminded me of oak leaves or blunt ended sticks.

DSCF7846

More triangles, and this time you can see the hollow centre.  There are frosty feathers in this one.  Notice how the triangles wander askew,  eccentric rather than concentric.

Opalescent shadows.  Several of these images are reminiscent of satellite images, or flying over the Canadian Shield in winter.

Nice Ice

My magical little ditch rarely disappoints.  There’s something about the deep pools of clear water in summer, the kaleidoscope of reflections in fall, and now the minute ice crystal formations in winter.  A few days of warmer weather followed by a bit of chill resulted in some amazing creations. All in miniature, these sights take some time and effort to see.

On the surface: yikes! a skating rink!

The ditch, looking rather ordinary.

Yet it also holds the extraordinary.

DSCF7845

A myriad of geometrical wonders.

The ice looks like a microscopic slide of something else… It’s own translucence creates a play of light and extra depth.

More ice shots tomorrow!  And the next day and the next.  I took quite a few 🙂
