  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.
