You can't get rid of it! play through the game and Cyrus, Jupiter and Mars will break it open revealing a new cave area that will take you to the peak.
No, but an ancient cave painting is.
You buy a gameshark ad cheat through it.
Go to the Galactic Veilstone Building, defeat Cyrus, and then the painting should be busted open.
Go through the cave
If you are playing platinum, you should defeat Cyrus and the commander and set the three mews free. If you go back to that area, the painting should be smashed and Looker should come and give you the mission to stop Cyrus, then send you off with a black flute (no special purpose, it just lowers the chances of a wild Pokemon encounter).
You need to of released the lakePokemon (Azelf, Mesphrit, and Uxie). The you can go there and the cave painting will be demolished.
Mount Cornet on Hearthome city side
you go to the cave with rock climb and stuff the go around.
To get to the top of Mt. Cornet you have to beat the team Galactic Eterna City and Veilstone buildings(otherwise there will be a cave painting blocking the path in Mt. Cornet) and enter Mt. Cornet from the Oreburg-Hearthrome City entrance(This is the ONLY entrance to the summit of Mt. Cornet. The other entrance takes you on the path to Snowpoint City). You need the HMs Rock Climb, Rock Smash, Strength, and Surf (Defog won't work in the cave). Also, when you get to the crumbled cave painting, Looker will give you a Black Flute, which lowers the chance of you running into wild pokemon.
you have to do the team galactic mission in velistone
No, but an ancient cave painting is.

Go to the Galactic Veilstone Building in Veilstone (of course in Veilstone) and beat Cyrus there. Then the painting should be busted open. I was stuck there too. I looked everywhere and couldn't find it
