Yeah I’ve heard of the one down south. I bet there is a third somewhere outside of North America too!

There is at least one other that I know of! There is also a Pyramid Lake near Los Angeles that I visited a few times as a kid (I was raised in LA). When I first moved to Tahoe and people told me that Lake Tahoe's water flowed down to Pyramid Lake, I thought they meant the one in LA, 450 miles away, lol. It blew my mind, but I eventually figured it out...
