I have searched through this area for many years and had mostly written it off as being a bunch of mossy, chossy slabs. My recent purchase of a mountain bike has allowed for a much more thorough search and has revealed some high quality boulders and some potential quality trad routes. According to the Massachusetts DCR website, this is technically part of the Gilbert Hills State Forest, but for most recreational users, it is known as the Wrentham State Forest.
Parking is available at several points on Taunton Street, including the main lot. Some of the rock is up to a mile hike from the parking but should be worth the effort.
It's in a small section near the mall. It looks way safer and not as hard in the pic than it is in person. Definitely needs to be cleaned via rappel. I have found a couple pedestal boulders, a big arrowheadish-shaped boulder somewhat close to 1a and a couple others in some odd sections. I have some pics, will track them down.
