Assuming that you did make the map, you were pretty accurate in describing that spire as unmissable. From where you were taking shelter, you could see the silvery shine almost as soon as the rain cleared. Half way up the tree, and you could see the wide spiral to the... well, either north or south. (With a few moments of sun watching, you could tell that it's to the north. Or the sun has suddenly decided to go backwards, but that's not a helpful assumption.)<br/><br/>Actually climbing, well, there's enough forest to tell you that you're somewhere in the lower half of the map.  Or upper half. Either way, going to the spire will take you past the center, and a bit past it is a river, and then most of the other drawings on the map.
