Ringlorn

Really? Clay seems to be an extremely common occurrence in the game. It looks like gray-blueish blots on the map and they are quite big and seem to be random (?). I have never came across clay underground, though.

The guide says fruit trees are supposed to spawn in pretty much all climates, but I haven't come across a single one yet. I'm not entirely sure what I'm looking for since I couldn't find any screenshots of them naturally spawned in the world. Are they supposed to be super-rare or something? Am I looking in wrong places?
