For many years, there was a lean to at the trail head for Little Jackson trail on Tumbledown mountain. There was also a lot of "car camping" sites, a rare thing in the southern part of Maine.
The entire area is now posted "no camping" and side trails have been permanently blocked off. There is still some parking for day hikers and the trails are still open.
So, you can "x" out those two camping symbols from your Gazateer. Sad, but it is a sign of our times.
