In California’s Central Valley, we are “blessed” with tule fog in the winter. Where did that name originate?
Tules, or tule land, is marshy or swampy land in northern California. The word comes from the Native American word tollin, meaning bulrush,” a plant that grows in these marshes. Eventually, the word was applied to the land itself. Presumably, tule fog is fog that forms over this type of land.”
