I believe that God has not given us an answer to this question as it might lead to a form of idolatry. I remember standing in the Princeton Cemetery at the foot of Jonathan Edward's grave (he is one of my heros of the faith) and thinking, my goodness, this is where that godly man's bones rest until the resurrection. I was so tempted to worship the place I was standing in because of it's proximity to a bunch of dead bones?!?! It was a strange feeling, and it was basically a temptation to idolatrous worship.
Now, how much more tempted might we be to worship a hunk or rock which we knew to be the location of that most glorious of events, the resurrection? I believe God has not told us this so that we are not tempted to worship the place.
