Pudding Stone, a variation of quartzite conglomerate.
The Blue Gus Chimney, (80 feet) "Photo Opportunity wall" follows the crack & face through every overhang.
The picture below shows what I call The Gumby Gate; A mentally, if not actual, crux - hard start.
(On Monday's one would go retrieve bail-gear; booty left the Gumbies, that could not get past the gate)
In this case, the triple overhang start, of the left side Arete & inside of the Blue Gus Chimney.
The other side of the picture is looking up the right side a crack-to-face, thru roof cap-stone, that my "Freak-Brother" looking friend is smiling on.
He is asking How Hard? having just passed the "Gumby-Gate" a 6-inch fist crack through that overhang & blocky corner start...(old school 5.10)

It is a long story . . . In short
The place has a decades-long history of climbing but was recently"declared closed" due to phone calls made by an ego-driven choss-hopper, Ken Roberts, who has been actively getting places closed to try and monopolize and then monetize the small bumps he has seen illegally beaten trails to, Claims to have - but- it is doubtful that he climbed while much of it was already climbed (decades ago) in where?
in New Jersey.
