We seek to resolve the tension in the literature regarding the presence ofradially segregated multiple populations in Galactic globular cluster M13.Previous studies of this nearby cluster have presented discordant results aboutthe degree of dynamical mixing in M13's inner region. Using ground-based (UBVI)photometry, we show that cumulative radial distributions of stars on the blueand red sides of the red giant branch are statistically identical.Interestingly, these results are obtained using data from large-aperture,ground-based telescopes as well as a more modestly-sized instrument, and bothare in agreement with previous work done using HST and Stromgren photometry.Results are derived using the C_{U,B,I} index, shown to be sensitive tocompositional differences. We discuss our conclusions that the chemicallydistinct populations within M13 may be dynamically mixed in the context ofpublished results from simulations.
