We argue that in cold, dense quark matter, in the limit of a large number of colors the ground state is unstable with respect to creation of a complicated quarkyonic chiral spiral state, in which both chiral and translational symmetries are spontaneously broken. The entire Fermi surface is covered with patches of quarkyonic chiral spirals, whose number increases as the quark density does. The low energy excitations are gapless, given by the Wess-Zumino-Novikov-Witten model plus transverse kinetic terms localized about different patches.
