More Hair Ice!

After an unusually mild January, we just started a bit of a cold snap. That means hair ice (frost flowers)!

Larger sticks can “grow” longer hair ice, but small sticks sometimes have especially pretty formations — especially if it wasn’t especially cold. This was a fairly small stick.

This is a much larger stick — really a branch, maybe 3-4″ diameter. The length of frost grown is comparable in this case, but the result isn’t as spectacular. However, it shows off the way the frost grows quite nicely!

Sometimes the tiniest sticks produce the prettiest formations — because you can actually see them! In a big, fluffy formation, it can be hard to see the individual strands of frost. This formation is on a tiny stick at the side of the driveway.

By contrast, here’s a frost flower that looks like a piece of cotton wool. It’s neat, but also hard to see enough detail to truly appreciate it.

I’ll close out with one that puts the “hair” in “hair ice”. They really do look like powdered ringlets! That’s because as the ice grows, it has a slight curve in one direction, resulting in a curl 🙂


Rob and I were lucky enough to visit the Big Island of Hawaii for a few days. We were even more lucky because KÄ«lauea had resumed erupting a few days before, and had a lovely lava lake in the crater!

We got up well before dawn to see it before dawn, and it was well worth the effort. It truly felt like looking into the heart of the earth.

Note that we didn’t have a good camera, so this was taken with my iPhone. It gives the right impression, but doesn’t do it justice. In reality, the “cracks” in the cooled surface lava are crisper and cleaner, but the incandescent light tends to overwhelm even a decent camera.

It probably takes a really good camera and maybe some filters to really capture it. As dawn broke, it was easier to catch a somewhat representative picture.

This was at 6:42 a.m., well into dawn. I’m really glad we arrived in full dark, but people arriving at this point still got a good show.

However, people arriving after full light got a completely different experience!

KÄ«lauea crater, the inner crater steaming and black. There is one visible spot of red, which is a lava fountain.
KÄ«lauea crater at full light. The inner crater that is steaming is the lava lake. The temperature hasn’t changed, but the liquid lava is no longer clearly visible. One lava fountain is visible at the top/center of the crater.

It was still amazing, but not nearly as awe-inspiring as clearly seeing the liquid lava.

Highly recommended, if you are lucky enough to get the chance!
