10 Mar 23 About a week back Jan shared with me a gorgeous photo of some ice taken in Sequim that was very different! I commented that I wish I had a shot like it in my collection but that I'd never even seen anything like it. She told me I was wrong and that we had seen some before and that I had taken some shots of it. I told her she was mistaken and she countered with why not look at ALL your photos and "see if I'm not right." A reasonable challenge as I just needed to look through maybe 200K or so images. So for this Friday's macro/close-up I'm sharing a copy of that shot I didn't have. Now it is nowhere the quality of the one she shared with me but I'm thinking most of you likely haven't seen this type of ice before so I'm sharing it anyway. It is called Hair ice and I've taken some material off the web to share with you about it. I do think you'll find it interesting. You'll need to zoom into 100%, maybe more, to really appreciate this type of ice. This is the only time I've ever encountered Hair ice. After you read the paragraph below you'll know everything about it.
"Hair ice, also known as ice wool or frost beard, is a type of ice that forms on dead wood and takes the shape of fine, silky hair. It is somewhat uncommon, and has been reported mostly at latitudes between 45 and 55 °N in broad leaf forests. The meteorologist (and discoverer of continental drift) Alfred Wegener described hair ice on wet dead wood in 1918, assuming some specific fungi as the catalyst, a theory mostly confirmed by Gerhart Wagner and Christian Mätzler in 2005. In 2015, the fungus Exidiopsis effusa was identified as key to the formation of hair ice. The fungus was found on every hair ice sample examined by the researchers, and disabling the fungus with fungicide or hot water prevented hair ice formation. The fungus shapes the ice into fine hairs through an uncertain mechanism and likely stabilizes it by providing a re-crystallization inhibitor similar to antifreeze proteins. Hair ice forms on moist, rotting wood from broad leaf trees when temperatures are slightly under 0 °C (32 °F) and the air is humid. The hairs appear to root at the mouth of wood rays (never on the bark), and their thickness is similar to the diameter of the wood ray channels. A piece of wood that produces hair ice once may continue to produce it over several years. Each of the smooth, silky hairs has a diameter of about 0.02 mm (0.0008 in) and a length of up to 20 cm (8 in). The hairs are brittle, but take the shape of curls and waves. They can maintain their shape for hours and sometimes days.This long lifetime indicates that something is preventing the small ice crystals from re-crystallizing into larger ones, since re-crystallization normally occurs very quickly at temperatures near 0 °C (32 °F)."
This is straight from the camera save for some cropping off of a section that was over exposed and blown out. Surprising Find Nikon D500; 18 - 200; Aperture Priority; ISO 400; 1 /160 sec @ f / 9.
