Vortex turbulence generated by high-amplitude second sound in superfluid /sup 4/He is observed. Features of the transition to turbulence are similar to those seen in dc superfluid flow experiments. The measured frequency dependence of the critical velocity agrees with the predictions of dynamic scaling theory. The measured temperature dependence is similar to that of dc counterflow.
