Unknown Cave of top of Mt. Coronet!

I found this by happenstance.  I wasn't looking for anything, but I found this:

 

On to of Mt. Coronet, in the first snowy section you come across, as you begin to pursue Cyrus and Team Galactic, you'll find this unknown cave.  You go up the Rock Climb areas and on the far right hand side of the screen, where there is a patch of grass with rock, with a Nugget inside it, STOP.  Look at the top, left of the screen and if you look carefully there are "Rock Smash" boulders and this unknown cavern entrance. 

 

I used my Pro Action Replay to use the" Run Anywhere code", and the "Rock Smash" boulders register as the ones everyonewhere, I can Smash them and everything, but I CANNOT enter the cave!  I ru through it with the code and when it's off, I run into a "wall"...

 

I can only speculate that this was originally designed to be a room to another shrne, perhaps to find Arceus or Dialga/Palkia according to which version is being played.  Maybe it was even used to find a legend that never made it into the game!
