It ices it so it doesn't get rutted.  On slushy days if you ice the whole run in it will make it super fast and keep it from getting rutted.

it melts the layer of snow on the top and the water refreezes because of the cold snow under it, making the top a super firm, icey layer.

i like it salted and then with a little snow on top.  Sometimes it feels weird right after its been done and not as easy to spin

salt first melts a small layer of snow which is turned into ice giving the skier/snobrdr mor speed

they do it to bring out the flavor of the snow used for the jump, in case anyone eats it

I heard paprika works wonders too.

But in all seriousness, it hardens up the kickers and makes them stronger and faster.

Usually, jumps are salted to help them keep their shape, either over night, or while people are hitting them when it's warm out.

Salt doesnt melt snow it just sucks all of the moisture out of it.

Snow is water, and the salt dissolves in it, which in turn lowers the freezing point. Hence, it melts the snow.

Usually snow melts at 0 degrees centigrade and above. Adding an amount of salt will let it melt at -5 degrees centigrade (for example). The freezing point depends on the concentration of salt in the water: more salt = lower freezing point, less salt = higher freezing point.

As the salt is only on the top layer, it melts the snow at the top layer, which then starts sipping down the snow underneath it. This is a water-salt solution which is sipping down and mixing with the snow that is underneath. Hence, the water-salt solution it is mixed with more water, lowering the concentration of salt. Less salt = higher freezing point = the water freezes again.

The end result is that the snow underneath is more compact and more icy.

high sodium levels are not good for the human body though, and can lead to excess weight gain...so make sure u dont salt ur take offs to much!
