We use hybrid simulations with particle protons and massless fluid electrons to investigate the evolution of a resonantly absorbed Alfvén wave. Around the resonant field line, the wave refracts or phase mixes so as to produce smaller perpendicular scales. When these scales approach 10 proton inertial lengths, we find that a rapid growth of mostly density fluctuations occurs which is driven by the "pump" Alfvén wave. This growth saturates by producing magnetosonic waves which then dissipate and give proton heating. Both parallel and perpendicular proton heating occurs. The proton heating continues until the pump Alfvén wave energy is nearly exhausted. We discuss how this process could limit density fluctuations to scales larger than the proton inertial length in solar corona holes where Alfvén waves are expected to undergo resonant absorption.
