Over the past 20 years of martian geologic investigations, paradigms for the origin of dendritic highland channels have altered between surface runoff and subsurface release with consequent headward erosion via sapping. Even the highest resolution Viking images have been unable to provide a definitive suite of geomorphic relations, primarily because of limited coverage, but also because of varied relations between drainage channels and their superposed materials. In light of the continuing difficulties for a unique solution to highland channel formation, and as a result of new field investigations of terrestrial paleochannels in the northeastern Sahara, it seems opportune to re-evaluate some of the basic principles by which martian channels are interpreted. Some of the terrestrial observations were made in the late 1970's by McCauley, Breed, and El-Baz, but these concentrated on the Viking lander observations and analogous terrestrial aeolian features. The past 20 years have seen a great increase in knowledge of the timing of climatic change in the northeast Sahara, as well as new field investigations of areas not visited before by scientists familiar with the problems of martian geomorphology. Following a brief summary of the late Tertiary history of the now hyperarid desert of northern Sudan and southern Egypt, I list four commonly stated (or tacitly assumed) guiding principles for martian channel interpretation and discuss the merits of applying these guides to channels on both Earth and Mars.
