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}/B > 4.5 {times} 10{sup 30}yr for the mode p {yields} 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} > 2 {times} 10{sup {minus}3} in data taken over almost three years.
