We have studied spin relaxation in the spin ice compound Dy2Ti2O7 throughmeasurements of the a.c. magnetic susceptibility. While the characteristic spinrelaxation time is thermally activated at high temperatures, it becomes almosttemperature independent below Tcross ~ 13 K, suggesting that quantum tunnelingdominates the relaxation process below that temperature. As the low-entropyspin ice state develops below Tice ~ 4 K, the spin relaxation time increasessharply with decreasing temperature, suggesting the emergence of a collectivedegree of freedom for which thermal relaxation processes again become importantas the spins become highly correlated
