<jats:title>Abstract</jats:title><jats:p>It has been proposed that erosional unloading by focused incision can be accommodated by flexural rebound, which in turn, potentially exerts a positive feedback on erosion. This paper presents morphometric data from the La Paz drainage basin in the Bolivian Andes to illustrate the effects of such a feedback mechanism between erosion and crustal bending. The Rio La Paz is a prominent system with the headwaters on the Altiplano and a trunk stream segment that cuts across the Cordillera Real thereby connecting large portions of the Altiplano with the Amazon Basin. The flexural feedback model explains why all drainages beyond the watershed disperse their waters to the Altiplano. It also provides an explanation for the presence of the highest peaks just next to the location where the La Paz River cuts into the bedrock across the Cordillera Real.</jats:p>
