The Soudan 2 underground detector is a large fine-grained tracking calorimeter comprised of long drift tubes read out by proportional wires. It is surrounded by a proportional tube shield. Preliminary nucleon decay results with 0.5 fiducial kT-yr exposure give 90% CL lower limits of [tau]/[ital B][gt]4.5[times]10[sup 30] yr for the mode [ital p][r arrow][ital K][sup +][nu]. A search for GUT magnetic monopoles making highly ionizing tracks yielded a 90% CL upper flux limit of 8.7[times]10[sup [minus]15] cm[sup [minus]2] s[sup [minus]1] sr[sup [minus]1] for monopole velocities of [beta][gt]2[times]10[sup [minus]3] in data taken over almost three years.
