Perhaps the most unusual ornament in the White House collection, this ornament depicts the Historic Entrance to Mammoth Cave National Park. It was created by Ranger John Yakel.
Starting with a five-inch ball, Ranger Yakel sliced a hole in the side of it and applied papier-mâché to depict layers of limestone at the Historic Entrance to the cave; he dripped hot glue over the “mouth of the cave” to create the spring, and applied modeling shrubbery to the top of the ball for the forest.
