Use these Warnings from Nature to Avoid Emergencies or Disasters

Be careful of snow cracks!

If you are somebody that loves skiing and spending time in the snow, then one of the best things you can watch out for is cracks or hollows in the snow. These cracks can indicate unstable or loose snow, and it would be best for you to avoid these as they could be hiding caverns or valleys—places you do not want to find yourself in.
