Drawings and Markings

[CapeCod]

Went out to Stony Kill Falls last week and ran into someone who told me if I follow the Stony creek the opposite way back from the falls that after a mile or so on the left side or the creek I would see a drawing on a rock face of a Jaguar and a little further up a bear on another rock face. He said it would be good sized and very hard to miss. Does anyone know any more information about these "drawings" or if there would be an easier way to get to them? Also heard rumors years ago somewhere on the preserve there is something chiseled into another rock face, some kind of strange lettering??? Any information about either one of these topics I would find interesting. Thanks in advance.
