"The Virgin" (5.10c) climbs the diagonal line from the base of the left most tree, across the dark angel, to the top of "English Hanging Garden." A fine thin line, but often overlooked.
I remember climbing for years at Big Rocks starting in the 70's. I remember the Trough was once rated 5.4 now I see it rated 5.6. I have climb almost every route at Big Rocks. I use to watch Lynn Hill climb at Big Rocks and also in the 70's the climbers than had to park and hike the trail over to the rock . Now, you can just drive up and belay from your car.The Trought was always a excellent introduction in lead climbing with protection bolts all the way up the face.
