Trifling rock is the first formation on the right side of Slab Canyon. This is the long formation to the south of Laugh Rock. An old abandoned, rusty truck marks the entrance to this canyon. Remains of an old dirt road lead into the canyon, ending at an old foundation.
From the Wonderland Parking area, head toward the stamp mill. Shortly after passing the turn off heading to Uncle Willie's, a rusty truck will be seen off to the left. From there an old dirt road leads into the canyon. Follow this for a ways then head east, across the desert to this crag.
