The SpARCS survey was designed to detect large numbers of clusters of galaxies at z > 1. Covering the 50 square degrees of Spitzer SWIRE Legacy Fields, it is one of the largest surveys of its kind. Over the past few years, the SpARCS team has been examining the properties of galaxies in these clusters though multi-wavelength imaging and multi-object spectroscopy. In this talk, I will discuss what we are learning about galaxy evolution in these the densest of environments. I will also discuss our plans to push these studies to even higher redshifts where it seems that drastic changes to the galaxy population in clusters is occurring.
