Visited the Paterson Museum and the Great Falls this month. Lots of great exhibits on the Lenape, local geology and Paterson's industrial history (including a great collection of Colt firearms).

I believe that the carved stone bearing the name of legendary archeologist Max Schrabish might have been his gravestone. (He discovered the rock shelter near the Clove at High Mountain  and hundreds of other rock shelters throughout the Northeast.)

You can learn more here -- but call before you go... Best route to get there is probably via Route 80.
