Sorry those words didn't help! I need simple ones! Again I need a geography term that starts with the letter Y that is not a place or river.

Ms. Sue · Answer

That's all there are. I checked a couple other geographical dictionaries and found nothing to help you. I recommend you use yardang or yazoo tributary.
