You're assuming that a future society will have the same interest as we do in conserving physical artifacts. A physical structure like a coastline takes up a lot of space and matter compared to the amount useful information it holds. If we're going to be efficient about it, you could map California down to the nearest micrometer and save the data to some form of very high density storage.
