Only the Mohonk Preserve can place new bolts at the Gunks; climbers are prohibited from doing so. So requests for bolted anchors have to be sent to the Preserve.

From the Preserve's climbing policy:

"In order to maintain the cliffs as far as possible in their natural state, however, the Preserve forbids all environmentally damaging climbing practices. These include trundling rocks, chipping holds, affixing new holds, cutting trees, and placing new bolts and pitons. The Preserve may, with consultation of the Land Stewardship Committee, add or replace permanent anchors if they improve climber safety. Replacement of such anchors may also minimize damage to vegetation / habitat, reduce visual clutter, and reduce maintenance cycles of existing fixed anchors."

MP will not be placing any more bolts from what i was told

The twisted logic is this: only the Preserve can place or replace bolts but the Preserve absolutely won't place or replace any non-bolts. So if there's a tatty non-bolt anchor, it's ours to deal with, but in a non-bolt way.

Frankly, if there were pins and nuts there then it sounds like you could put in your own gear, clip it with your own slings, and clean it up when you left. Just because there's a fixed anchor doesn't mean you have to use it.

Leaving in an uncontrolled, rapid and groundward direction on rappel once that temporary gear is removed particularly concerns me. Leaving additional backup gear is a solution, but something more permanent is preferable IMO.
