There exists an entropy-preserving equivariant surjective map from the d-dimensional critical sandpile model to a certain closed, shift-invariant subgroup of the Cartesian product of infinitely many cycles, one for each node of the d-dimensional integer lattice (the 'harmonic model'). A similar map can be constructed for the dissipative abelian sandpile model and be used to prove uniqueness and the Bernoulli property of the measure of maximal entropy for that model.
