We study the Ising antiferromagnet on the triangular lattice which areinteracting along three different directions via two $J$-bonds and oneanisotropic $J'$-bond with $J' \ge J$. Although its finite temperature statehas long been considered as simply disordered, we find a systematic generationof a ferromagnetic $J'$-bonds named "good defects" each carrying the energy$2\delta_J\equiv 2(J'-J)$. They exhibit an eminent correlation which isregarded as a network or a soft lattice. The specific heat shows a universalpeak at $T^* \sim \delta_J$ and the corresponding energy follows the activationtype of temperature-dependence with an excitation gap $2\delta_J$. Energeticsand the crossover between this particular two-dimensional state and the otherdisordered or one-dimensional states are discussed.
