The day was cold but even though the temperature was barely above zero, the sunshine melted some of the icicles, causing them to fall off the roof. The sidewalk had pieces of the icicles but at least none of them were as huge as these on the shore of Lake Superior since it would be hard to open the door with those pieces blocking the way.
The cold front arrived and it is a chilly start to the day so the ice formations do not have to worry about melting today, but then they won’t be growing longer either without some running water.
On the Apostle Islands National Lakeshore Facebook page, they made this comment about the ice caves. “As the weather warms up, the walk to the ice caves will be more pleasant – but that also means that icicles will start melting and falling and there will be more slush on the ice – make sure not to stand under ice formations and wear waterproof boots – with ice cleats!”
And standing under or near one of the icicles could be very hazardous to one’s health, as some like this one, are an average of three and half to four feet in diameter and even larger at the base. Even this one has a section which is close to six feet across so it would have a bit of an impact if it hit you. It appears it make a bit of an impact on the ice surface and created a crack in the ice.
Icicles come in all shapes and sizes and they can reflect the view around them as well as reflecting a tiny star by the captured sunlight. But even though they are reflecting the sunlight, they are not giving off any heat and to me they are only reflecting the bitter cold temperatures.
