Cant really tell anything buy your pict.
Is this a new snowboard to you ?
Then it might be normal, doubt it.
Look online for Photos of same model.
If not and you just noticed?
While trying not to break it, put that end of the board on some shag and push down on the other end.
Sound like it is cracking or see to much flex there?
If the answer is yes then it is not normal.
