We present progressmade by the Hadron SpectrumCollaboration (HSC) in determining the tower
of excited nucleon states using 2+1-flavor anisotropic clover lattices. The HSC has been investigating
interpolating operators projected into irreducible representations of the cubic group in
order to better calculate two-point correlators for nucleon spectroscopy; results are published for
quenched and 2-flavor anisotropic Wilson lattices. In this work, we present the latest results using
a new technique, distillation, which allows us to reach higher statistics than before. Future
directions will be outlined at the end.
