Not that this is a popular area but the bears island area of the MD side of great falls is closed to climbing. We decided to check it out while visiting some friends in DC. It's not posted anywhere on site but the ranger quickly stopped us. He did say that we are welcome to free climb, just not ropes allowed..... Thanks.
Did the ranger say why or when this went into effect? I have climbed there several times, as recently as this past spring, and no one ever said anything. Then again, I don't remember seeing any rangers while out there.
