A crystal graph is a colored directed graph satisfying certain
axioms. Stembridge gave a "local characterization" of those
crystal graphs attached to highest weight modules of Lie algebras
of simply laced type. In other words, he gave a purely graph-theoretic
way of recognizing those graphs.
In this talk, we observe another property these graphs have.
Although not a characterizing property, it is surprising in its
