Who is the largest private landowner in the US?

I'm curious to know, who holds the title of the largest private landowner in the United States? Is it an individual, a corporation, or perhaps a family dynasty that has been amassing land for generations? And what kind of land holdings do they possess - vast tracts of farmland, sprawling ranches, or perhaps a mix of both? What are the implications of this level of land ownership on the local communities and the broader economy? It's a fascinating topic, and I'm eager to learn more.
