We have studied the ultrasonic velocity and ac susceptibility of URu2Si2 in magnetic fields up to 45 T. The resulting phase diagram reveals new phase boundaries that place strong constraints on theories of hidden order for this material. Furthermore, a significant difference between the constructed H-T phase diagram and that extracted from earlier pulsed field measurements is explained in terms of a large magnetocaloric effect. An offshoot of this analysis is that care should be taken in interpreting pulsed field measurements.
