M35 (NGC 2168) is rich, young, and in some regards a bet­ter laboratory for stellar cluster research at 100 million years than the Pleiades. Yet, while M35 has been the subject of intriguing photometric, astrometric, and theoretical studies, to the best of our knowledge no pub­lished CCD-based photometry exists for this cluster. We have obtained relatively wide-field (23' x23') precise UBVRJ CCD photometry for M35 as part of the WIYN Open Cluster Study (WOCS) at the 0.9m telescope at Kitt Peak National Observatory. The photometry extends from the main sequence turn off to beyond V = 19. We find that M35 is ~ 100 Myrs old, with (m-M)v = 10.25, and E(B-V)=0.3 based on fitting Yale isochrones. We also perform a differential comparison between M35 and the Pleiades, and we explore the cluster dynamical state.
