Lake Tahoe’s Emerald Bay was once the site of the Emerald Bay Resort. I believe the resort was in operation from the late 1800’s until around 1920, but I’m not sure about the exact dates.
When the resort was dismantled, a lot stuff was shoved into the bay, including a boat dock and diving platform and about half a dozen (7 if I remember right) small rowing dories that remain on the bottom.
Rumor has it that a Model A Ford is down there too. In the coming months, I will try to prove that.
