In the crisp mornings of winter, when the world is blanketed in a glistening coat of frost, nature often reveals one of its most captivating spectacles: frost spikes. These delicate, spike-like structures that adorn plants and other surfaces bring an otherworldly beauty to the landscape
Hoar Frost Spikes
Nature is pretty awesome! When I wake up to an otherworldly beauty first I admire it, then I question exactly what it is.
Which lead me to spend a few hours outside exploring the plant life and trees. Then unleashing my questions online to explore the reasoning.
This phenomenon is known as frost spikes or hoar frost spikes. They emerge under specific conditions when frost forms on plants, creating intricate, spike-like formations. Each spike is a testament to the intricate dance of temperature, humidity, and moisture in the atmosphere. As water vapor freezes directly onto surfaces, it bypasses the liquid phase, allowing ice crystals to grow in elongated shapes, resembling delicate needles or spears.

There are a few different types of frost spikes:
- Hoar Frost Spikes: Hoar frost spikes occur when water vapor in the air condenses directly into ice crystals on surfaces, such as plant stems and leaves, bypassing the liquid phase. When this happens, the ice crystals can form elongated, spike-like structures.
- Needle Ice: Needle ice forms when the temperature of the soil or ground is above freezing, but the air temperature is below freezing. Moisture from the soil is drawn up through capillary action and freezes upon contact with the colder air, forming needle-like ice crystals. These crystals can sometimes appear on plant stems, creating a spiky appearance.
- Hair Ice: Hair ice is a rare phenomenon that occurs under specific conditions. It forms on the surface of dead wood, particularly in humid conditions when the air temperature is slightly below freezing. Ice crystals grow from the wood and arrange themselves in fine, hair-like strands, giving the appearance of silky, hair-like structures.
These types of frost spikes are visually striking and can create beautiful, intricate patterns on plants and other surfaces. They are often observed in cold, humid environments during the winter months.
Hair Ice
One of the areas I visited in the past couple of days had gorgeous hair ice on all the dead wood of the plants. Over my entire lifetime, I have not had the opportunity to witness this rare phenomenon.
All photos above were taken in one section of Bay Beach Wildlife Sanctuary in Green Bay, Wisconsin. The area the hair ice was found in was harbored by trees.

This area is around the UWGB Campus trail system. Which look vastly different from what I saw in the city.
Photos were taken on the Squirrel and Racoon trail off East Shore Drive. The further you got away from the city the spiker the plant life looked.

Photos were taken at various locations such as Bay Beach Wildlife in Green Bay, Wisconsin, and a little further down the road at the Squirrel and Raccoon trail off East Shore Drive. I believe the top photo to be rime ice because the berries had a frosty appearance and the ice has a granular texture to it. But all photos were taken within a 1/2 mile of each other with each environment a little different. Like an open field versus a harbored interior with thicker tree limb cover.
