ABSTRACT
We construct a Young wall model for higher level -type adjoint crystals. The Young walls and reduced Young walls are defined in connection with affine energy function. We prove that the affine crystal consisting of reduced Young walls provides a realization of highest weight crystals B(λ) and B(∞).
