We test the cooling algorithm with gluonic and staggered hadronic spectroscopy on SU(3) gauge field configurations generated with two flavors of staggered dynamical fermions. We find cooling is not reliable as the basis for improved hadronic operators. We also find that performing cooling sweeps to reveal more clearly the topological properties of the gauge fields eliminates the spin structure of the hadron spectrum.
