This huge boulder, perched on a steep hillside just downslope from the Hardy Boy Boulder, is home to a number of high-quality boulder problems including Momma's In New York (V2) a tall and striking arete and J. Elvis (V2+) a slabby, thin face.
Walk the upper paved road to the northern corner of Mt. Rubidoux and then follow a steep trail to the base.
