Frost Columns and Ferns
/There was frosty morning last weekend at our house, and I photographed the crystals about 30 minutes after sunrise…in a hurry because the temperature was 20 degrees Fahrenheit, and I hadn’t put on my coat! There was frost on the lamb’s ear and an old leaf that looked like crystals of sugar.
\I was more interested in finding more complex crystals. Our wrought iron table had frost all around the outer edge.
The first ones I saw were columns…sometimes in clumps…emanating from films of ice (that might have started out as water).
I was surprised to find very different crystals on the other side of the table! They were a lot like the frost ferns I posted about back in January. They were not quite as large, and they grew out of a thin film of ice rather than as ‘fronds’ around a common center as they had in January.
I wondered what caused the crystals to be different on opposite sides of the table. In the past, I found column type crystals when the temperature was closer to 30…the ‘ferns’ when it was 20 or below. The columns were on the side of the table closer to the hollies and some cedars; the ‘ferns’ were on the side next to the posts supporting the deck stairs. Could the vegetation be creating a slightly warmer temperature? Maybe next time – I’ll take a thermometer out to test that idea!
All photos were taken with my Samsung Galaxy S10e (most are at 8x magnification).
