BEDFISH: Revising an old Idea for Classifying Surface Ice Forms

January 31st, 2010
It often seems like people refer to any kind of ice stuck on something as frost. If one looks in books or the Internet, one can usually find a specific term for the many different and interesting ice formations, but a term used by one group of people… more »

Like Seashells at a Seashore

January 30th, 2010
This morning it just barely dipped below freezing, the first time in several days. Off I went to the usual black cars. And once again the frost to me looked like things I’d seen before. I decided to take a few pictures anyway, and once again I was… more »

Ice on the Rocks

January 27th, 2010
On the morning of December 7 of 2008, I saw a small yet distinct white patch on the ground amongst the dirty brown crunchy soil-ice columns in a rice field. If I hadn’t been looking straight at it, I would have missed it. Crouching down and clearing… more »

Eyes and Dry Moats

January 22nd, 2010
Though I appreciate seeing the old and familiar, when I venture outside on frosty mornings, I usually see at least three unexpected things. Three unexpected things before breakfast. A few days ago, the frost at first appeared more hoary than curvy, but… more »

The Maltese Cross in Pond Ice

January 21st, 2010
A few days after my encounter with the pawprints and grey muck, one of the ponds did freeze over. After me and my camera spent about 30 minutes admiring this rare event, I went and ruined the complete glaze job by punching a hole in it. Although the top… more »

Strange Pawprints in the Ice

January 15th, 2010
On account of the recent cold spell, I went up the hill behind us in search of a glazed-over pond. Ponds can have interesting freezing patterns and, if the ice is thick enough, a little excitement. I've never seen these ponds freeze, but then again,… more »

Snakeskin Frost and Other Curiosities

January 12th, 2010
You can see a lot on just one black car. The nearly uniform appearance of white frost shows, upon closer inspection, a variety of forms. The first black car of yesterday morning didn’t seem so striking, and I considered passing it by. But, thinking of… more »

Frost World

January 9th, 2010
Whenever I am taking a picture on macro near the maximum close-up to an object, the aperture on my little Canon automatically sets to the maximum size, which means that the resulting  images  are in focus only at the center. Ever since I got the camera… more »

They Came From Out of the Tub

January 8th, 2010
Last night it rained, but the skies cleared before morning, letting the air temperature drop to about 2 degrees C. The weather, it seemed, would be perfect for lacy white frost patterns on cars. But it didn't quite turn out that way. A little bit before… more »

Ice of Hearts

December 28th, 2009
Back when I lived in Boulder CO, I worked with Charles Knight on developing a new way to grow ice crystals for experimental study. I knew that the problem with most methods was twofold: there were too many crystals too close together to be able to learn… more »
