We report on a study of hadron thermodynamics with two flavors of Wilsonquarks on 12^3x6 lattices. We have studied the crossover between the high andlow temperature regimes for three values of the hopping parameter, kappa=0.16,0.17, and 0.18. At each of these values of kappa we have carried out spectrumcalculations on 12^3x24 lattices for two values of the gauge coupling in thevicinity of the crossover in order to set an energy scale for ourthermodynamics calculations and to determine the critical value of the gaugecoupling for which the pion and quark masses vanish. For kappa=0.17 and 0.18 wefind coexistence between the high and low temperature regimes over 1,000simulation time units indicating either that the equilibration time isextremely long or that there is a possibility of a first order phasetransition. The pion mass is large at the crossover values of the gaugecoupling, but the crossover curve has moved closer to the critical curve alongwhich the pion and quark masses vanish, than it was on lattices with four timeslices. In addition, values of the dimensionless quantity T_c/m_rho are incloser agreement with those for staggered quarks than was the case at N_t=4.
