Rare snow rollers have been spotted in fields across northern Vermont recently, creating a unique and beautiful sight for locals. These cylindrical formations are a rare phenomenon that only occur under specific conditions.
For snow rollers to form, there needs to be a thin layer of wet snow on top of icy or compacted snow. The snow on top must be able to cling to itself without sticking to the snow beneath it, allowing the formations to roll and glide. Additionally, the perfect amount of wind is required to get the snow to start curling up into cylinders without tearing them apart.
As the wind pushes the snow rollers across fields or they gently roll down hills, they pick up more snow and grow in size. This process is similar to rolling a snowball to create a snowman. The unique combination of snow quality, wind conditions, and terrain make snow rollers a rare and fascinating natural phenomenon to witness.
Residents of northern Vermont have been captivated by the beauty of these snow rollers and have been sharing photos and videos of the formations on social media. While they are a fleeting sight, locals are enjoying this rare occurrence in nature.
