It might be an old Mammut ring bolt. The route Max Flex, located on the Meat Puppets Wall (1st Pullout on the loop road) is/was equipped with these bolts.

That pin at the top is pretty intimidating to lower from... craziest thing I ever saw at the top of a route for sure.
It is possible to 4th class down into the notch between the top of the crag and the other formation. From there it is a short scramble down to the base on the back side of the crag.
