The ARIANNA experiment in Antarctica is targeted at detecting the radio emission of neutrinointeractions in the ice. However, due to their antennas being deployed close to the surface, ARIANNAstations have routinely been used for cosmic ray detection. These fully self-triggeredevents have in-turn been used to improve reconstruction algorithms and to provide a proof-ofprinciplefor neutrino detection and reconstruction. We will present the detected events and theircharacteristics. Also, we will elaborate on novel algorithms to reconstruct the cosmic-ray energyfrom a single station and to reconstruct the signal polarization from distributed antennas. Whilenecessary for sparse neutrino arrays, these methods also provide new opportunities for stand-alonecosmic ray arrays to improve event statistics and reconstruction quality.
