I'll go ahead and close the loop on this… It's the Great Saltair pavilion. A resort that was built on the shores of the Great Salt Lake in the late 1800s. It burned to the ground 100 years ago next year. "The Coney Island of the West" It featured swimming, the world's largest dance floor, a roller coaster, carousel, midway games, billiards, food, and more. Always wondered what it would be like to see it. So I thought I'd give myself a little glimpse with some 3D magic. More on this later…
