Published accounts of outburst floods from glacier-dammed lakes show that a significant number of such floods are associated not with drainage through a tunnel incised into the basal ice, the process generally assumed, but rather with ice-marginal drainage, mechanical failure of part of the ice dam, or both. The AA. develop a simple physical model of the breach-widening process for non-tunnel floods. Calculations based on the model simulate quite well outbursts from Lake George, Alaska
