We analyze the rotational demagnetization of artificial spin ice, a recentlyrealized array of nanoscale single-domain ferromagnetic islands.Demagnetization does not anneal this model system into its anti-ferromagneticground state: the moments have a static disordered configuration similar to thefrozen state of the spin ice materials. We demonstrate that this athermalsystem has an effective extensive degeneracy and we introduce a formalism thatcan predict the populations of local states in this ice-like system with noadjustable parameters.Comment: 4 pages, 4 figures.
