it evolves when you trade with someone
No. It will evolve into a Golem.
look near rocks or evolve geodude
Get yourself a geodude. Level it up until it reaches the level were it evolves into a graveler. This is when it can be tricky. You now need to trade it with someone else. Once they get the graveler, it will evolve. Then just trade back : )
None, Graveler doesn't evolve into Golem through leveling but only through trading with another person who has the game.
