One addition or comment, if you go with something like 60% chance of finding something interesting when searching a hex, don't make it a one and done thing. Even when searched, it would be easy to miss something like a cave or a building or faierie ring. So each time the square is searched, allow a new role to see if something is discovered this time around. Maybe reducing the chance by 10% each time to prevent one hex from containing a thousand things and to give reason to more to the next hex.
