  Using a correlation matrix analysis consisting of a variety of smearings, the
CSSM Lattice collaboration has successfully isolated states associated with the
Roper resonance and other "exotic" excited states such as the $\Lambda(1405)$
on the lattice at near-physical pion masses. We explore the nature of the Roper
by examining the eigenvectors that arise from the variational analysis,
demonstrating that the Roper state is dominated by the $\chi_1$ nucleon
interpolator and only poorly couples to $\chi_2.$ By examining the probability
distribution of the Roper on the lattice, we find a structure consistent with a
constituent quark model. In particular, the Roper $d$-quark wave function
contains a single node consistent with a $2S$ state. A detailed comparison with
constituent quark model wave functions is carried out, validating the approach
of accessing these states by constructing a variational basis composed of
different levels of fermion source and sink smearing.
