It’s a lake. I’ve never been to it. It’s pink & in Western Australia near the town of Esperance. I know this because I posted my back porch view on a FB site called “View From My Window,” & somebody commented on it from Esperance. So during COVID times, what’s one to do? Of course look up Esperance, Australia, & see what cool stuff they have there. Kangaroos on white sand beaches and a lake, a pink lake. It’s due to its salinity but it is pink. Cool.
