Not totally gone.
During spring and summer we have made five or six trips to the cabin (Read: lake) and each time north I have been accompanied by the anxiety of experiencing no beach when we get there.
My expectations have been so pessimistic that almost every time upon arrival I have been mildly encouraged: there is some sand still there and during our most recent trip in early September we were back to having a beach fire on, well, a beach.
Our diminished beach is partly a function of the rising lake, but not totally. Currents and sand flows that have been very good to us over the decades have moved on.
