Cartographers
Can I draw over a ruins space when no ruins card was revealed?
A designer or publisher post on BGG answers this directly.

Yes. An unfilled ruin is just an empty space, so any shape, including an ambush monster on your map, may cover it at any time. The downside is that you may have no open ruin left when a ruins card comes up.
