We measured the elastic constants of the heavy fermion YbAgGe using resonant ultrasound spectroscopy at temperatures from 300K to 0.5K and magnetic fields to 7T. As a function of magnetic field and below 7K, the elastic constants show strong non-monotonic behavior, suggesting a field-induced quantum critical point. Only at the lowest magnetic fields is there a strong temperature dependence.
