In these proceedings, we discuss recent results from d. +. Au collisions in PHENIX ridge related measurements and their possible hydrodynamic origin. We present the v2 at midrapidity and measurements of the pseudorapidity dependence of the ridge, distinguishing between the d-going and Au-going directions. We investigate the possible geometrical origin by comparing v2 in d. +. Au to that in p. +. Pb, Au. +. Au and Pb. +. Pb collisions. Future plans to clarify the role of geometry in small collision systems at RHIC are discussed.
