Using the tail of the distribution of the depth of shower maxima
observed with the Pierre Auger Observatory, we derive an estimate of
the proton-air cross section for particle production at center-of-mass
energies of 57 TeV. Air showers observed with the fluorescence
detector and at least one station of the surface array are analyzed in
the energy range from 10^18 to 10^18.5 eV. Systematic uncertainties of
the cross section estimate arising from the limited knowledge of the
primary mass composition, the need of using shower simulations, and
the selection of showers are studied in detail.
