Spent three lives running around my world, checking hillsides and such, and have yet to encounter any clay. Honestly, I think if they're going to be covered by grass in the world, some unique feature needs to mark their location. Also, clay should definitely spawn near/in bodies of water at some regularity, as that occurs in real life as well. As for unique features, maybe clay groups could be slightly raised compared to the nearby soil, as the dirt compacts and clay does not.
