This gigantic cliff is simply stunning standing at the base. It's easy to see how this 300ft tall cliff is the largest in the state... AND THE MOST DANGEROUS. This area was created from extensive quarrying operations. As a result the base is covered in shrapnel from massive blocks disloging and exploding at the base. It is NOT recommended that anyone belay at the base of any of these cliffs. Even lowering down can cause problems with the rope dislodging flakes and blocks that could injure, cut ropes, and kill.
From Merritt Parkway take exit 59 and travel north on Whalley Ave (rt 69). Take a right onto Bradley Rd, at T intersection turn left continuing on Bradley Rd. Follow to end and park. Scramble up talus field up and left towards the base of the quarry. There is also the main entrance on Wintergreen Ave which will allow you to drive north on Baldwin Ave to reach the top of the quarry.
I grew up here in the 1960s and 70s (I can see my house in the aerial photo on the main area page) and as an interesting aside, sometime around 1976 a U-Haul truck was driven/pushed off the top of the Barker Daniel Wall (we just called it the quarry wall back then). Baldwin Drive runs really close to the edge at the top and some kids, I'm guessing, stole the truck and broke down the chain-link fence and did the deed. (I swear I was not involved.) The wreckage was visible for a really long time (years as I recall, it didn't quite make it to the bottom and must have been a real pain to clean up.)

The driving up possibility on Baldwin Drive has been shut down since the day the Uhaul got pushed off the cliff but it is an easy bike ride, 10 minutes on a paved road. Its actually a really nice bike ride on Baldwin drive if you do the whole road and come back on the road down below past Lake Wintergreen. Some sweet boulder along the way as well.
