In a large punch bowl, combine lemonade, orange juice, sparkling water (or soda), and lime juice. Stir well. Top with a generous layer of crushed ice to create a snowy effect. Arrange lemon, lime, and orange slices on the surface of the punch, along with fresh mint sprigs for garnish. Place a large wooden ladle in the bowl for serving, and fill individual glasses with punch. Garnish each glass with a citrus slice and a mint sprig.
