Hoarfrost And Pitch Pine


January 29, 2026

A picture from Monday of this week, January 26th. First thing that morning, I looked out hoping to find trees coated with beautiful ice. Instead I saw something just as lovely but more subtle, hoarfrost.

Hoarfrost happens when surfaces, such as these Pitch Pine needles (Pinus rigida), become colder than 32°, the freezing temperature. Water vapor then hits the very cold surfaces and the water in the air immediately becomes ice crystals, skipping the liquid phase. The ice crystals create a unique appearance, forming structures that are needle or feather like.

If you would like to read more, or see more of my photos of gorgeous hoarfrost, check out: brendaclem.com/hoarfrost/ which I put together a few years ago.

  1. Beautiful picture, Brenda! And I never knew that about hoarfrost—always thought it was just an arcane word for frost.

    • Hi Grace, hoping you are safe, warm, and able to get out. Although we usually dig ourselves out of our 1/10 mile lane, this storm has been daunting with its “snowcrete” and resorted to ask a neighbor to bring up his heavy duty Bobcat Skid Steer which made those HUGE chunks look so very easy to move! Isn’t the hoarfrost amazingly beautiful?!! I hope you had time to pull up: brendaclem.com/hoarfrost/
      So very glad that you read my posts!

    • Hi Ken, super to hear from you. I hope you are doing well, all dug out and staying warm. I can’t believe how COLD it is staying!
      Thank you so much for your kind words. I thoroughly enjoy doing a blog post each evening, and when I find something that is really interesting to me — I really get going! But I try very hard to keep things short!
      So very glad you read my posts!
