I present highlights of recent CLEO studies on the Upsilon(1S), Upsilon(2S), and Upsilon(3S). The preliminary results presented here include the first observation of a hadronic cascade in the Upsilon system not involving pions, Upsilon(3S) to gamma chi(b1,2)(2P) followed by chi(b1,2)(2P) to omega Upsilon(1S). I also present preliminary results on a search for inclusive psi production in Upsilon(1S) decays. I end with a search for nine different two body hadronic decays of the Upsilon(nS), n=1,2,3, resulting in the discovery of two such decays, and vastly improved upper limits on the branching ratios of the rest.
