The AA. explore here the research questions of if and how granitic rock pediments respond to the transition from rimming endorheic basins to bordering through-flowing streams. This paper presents the results of a pilot investigation into the response of granitic pediments to drainage basin evolution and episodic base-level adjustment in the Sonoran Desert, where pediments are ubiquitous. The AA. focus here on the lower Salt and Verde rivers, south-central Arizona. Using fieldwork, supplemented by aerial photography and electron microscope studies, they present evidence that the observed granitic rock pediments are not inherited landforms from an ancient wet period of time, as some have suggested. Instead, these pediments respond actively to post-integration base-level changes
