We describe a recent calculation of the hadron spectrum with two flavors of staggered dynamical quarks with a gauge coupling 6/g{sup 2} = 5.60 and quark masses of 0.025 and 0.01. The gauge fields were generated using the hybrid algorithm on a 12{sup 4} lattice that was doubled or quadrupoled to calculate hadron propagators. 5 refs., 5 figs.
