- "I need to understand the properties of an ancient Monolith. Now, I've learned it was buried in the Yucatán after being dragged around the Earth for a few hundred years."
- ―Leo Fitz to Yusef Hadad[src]
During the 19th Century, the ancient artifact known as the Monolith was buried somewhere in Yucatán, where it remained hidden for several decades. 
A Yucatán ranch was previously owned by Gene and Alice Hernandez. When the Hernandezes died, ownership of the place was transferred to Dale and Stacey Yorkes.
