  Although the most luminous class of neutron star low mass X-ray binaries,
known as Z sources, have been well studied, their behavior is not fully
understood. In particular, what causes these sources to trace out the
characteristic Z-shaped pattern on color-color or hardness-intensity diagrams
is not well known. By studying the physical properties of the different
spectral states of these sources, we may better understand such variability.
With that goal in mind, we present a recent NuSTAR observation of the Z source
GX 349+2, which spans approximately 2 days, and covers all its spectral states.
By creating a hardness-intensity diagram we were able to extract five spectra
and trace the change in spectral parameters throughout the Z-track. GX 349+2
shows a strong, broad Fe K$\alpha$ line in all states, regardless of the
continuum model used. Through modeling of the reflection spectrum and Fe
K$\alpha$ line we find that in most states the inner disk radius is consistent
with remaining unchanged at an average radius of 17.5 $R_g$ or 36.4 km for a
canonical 1.4 $M_\odot$ neutron star. During the brightest flaring branch,
however, the inner disk radius from reflection is not well constrained.
