R2.C(1/4) is the R2-Name of the two cusps between R2a and R2.1/4a. The corresponding cusps near R2.3/4a are the same except for the vertical reflection. The colloquial name "quad spiral valley" comes from the quadruple spirals that are prominent in the filaments of the mu-atoms on the child side of the cusp.
