The recent experimental observation of collective rotational bands up to I>60({Dirac_h}/2{pi}) in {sup 175}Hf presents theoretical challenges. It is shown here that total Routhian surface calculations are able to explain the yrast high-spin behavior, with collective oblate states favored at I{approx}35({Dirac_h}/2{pi}) and strongly deformed prolate states at the highest spins. The collective oblate rotation terminates in noncollective prolate states. Comparisons are made with ultimate cranker calculations, and theoretical quadrupole moments are evaluated.
