A Couple of Qestions About Ginnie

[ScubaRob]

Last time I dove Ginnie we took the Bone Room tunnel. We turned the dive at the 4th set of double arrows on the Bone Room line. Looking at the map it's a little hard to tell where that actually is. Can anyone help me out here?

Also on the 2nd dive we stayed on the main line. I counted 4 sets of double arrows here also. We went a little further than that. We turned the dive at the 900' arrow. It looks like on this dive we were just short of the maple leaf. I think this is where the Bone Room line rejoins with the main line. Is this correct?
