The walk will start from Mead's Quarry trailhead. You reach the Mead’s Quarry trailhead at 3518 Island Home Ave. by going past the entrance to Ijams Nature Center, down the hill on Island Home Ave., and turning right into the quarry site after crossing the train tracks.
From the Mead’s Quarry parking area, we'll follow Imery Trail, the broad gravel road south. We will pass through remains of the limestone operation. Proceed to the junction with The Ross Marble Quarry Trail. No trip to the Ross Marble Quarry is complete without a trip over the Rock Bridge to the Keyhole. A few steps further will be the Rock Bridge Trail a short 0.2 mile tail that goes over a bridge constructed with huge marble blocks so that the workers could readily get from one side of the quarry to the other. After taking in the impressive quarry walls from the top, we'll descend on the other side and find a short path that leads to a square notch called the Keyhole. The keyhole is large enough for a couple of people at a time to pass though and there are stairs on the other side that lead to the bottom of the quarry. The Keyhole path dead ends shortly at a wet area, a good place to look for frogs and salamanders. There is a grate over a cave entrance where you can peer in and see the underground stream that goes on to fill Mead’s Quarry with water. Go back to the Rock Bridge Trail and follow it around until it meets up with the Ross Mable Quarry Trail. Stay right and follow this trail around back to Imerys Trail. Turn right onto Imerys and proceed a 0.2 mile further to the Hayworth Trail. This short trail dead ends after a short 0.1 miles in the middle of impressive quarry walls and remnant giant blocks of marble all overgrown with vines and partially covered by leaves. It gives the impression of stumbling into ruins from some ancient civilization. The gated cave entrances here lead to the underground stream that fills Mead’s Quarry and is home to the rare and endangered Berry Cave Salamander. From here, we will retrace our path, omitting Rock Bridge back to the parking area at Mead’s Quarry.
