A measurement of the spectral index of Galactic Cosmic Ray (GCR) iron has been performed using the High Energy Gas Cherenkov Spectrometer (HEGCS). The spectral index of GCR iron, in the energy range 60 to 200 GeV/n, has been determined to be {alpha}=2.56{plus minus}0.11. This result indicates that the source spectrum of GCR iron is similar to that of other primary GCR nuclei as expected in the Standard Leaky Box Model.
