The electronic transport properties of an SNS junction formed by an InN nanowire (N) and Al contacts (S) with a superconducting transition temperature T_c ~ 0.92 K were investigated. As a function of dc bias, superconducting quasiparticle transport resonance peaks at E=2\Delta were observed, in agreement with BCS theory with 2\Delta(T=0) \equiv \Delta_0=275\mueV. Several additional transport resonances scaling linearly in energy were observed at high-bias above 2\Delta, up to E\simeq 15\Delta_0, consistent with McMillan-Rowell oscillations. The persistence of McMillan-Rowell oscillations at high-bias and under applied magnetic field were investigated.
