R2.C(1/3) is the R2-Name of the two cusps between R2a and R2.1/3a. The corresponding cusps near R2.2/3a are the same except for the vertical reflection. The colloquial name "Triple Spiral Valley" comes from the triple spirals that are prominent in the filaments of the mu-atoms on the child side of the cusp.
