Snow your roll... Slow down, there. Pace yourself. Snow rollers, also known as "snow bales," "wind snowballs," or "snow donuts," are the cold weather equivalent of tumbleweeds. They form when wind pushes snow across the ground, gathering it into a hollow cylinder, some might say, donuts? (Mmm...Donuts!) Larger snow rollers can be a few inches wide and travel a couple feet, leaving behind long trails in their wake. When winter comes around, it brings with it the opportunity to experience parks in a whole new way. Colder temperatures can present its own set of risks and can make your trip challenging if you are unprepared. Always take a moment to check the weather forecast on the day of your trip. Weather conditions can change very quickly and vary throughout a park. Keep in mind that precipitation, wind speed, and reduced daylight hours can also impact your trip during the winter.
