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.
