The gorge wall on the outside of some meander turns is noticeably steeper than the gorge walls on the inside of the meander turn. For example, see “Cottonwood Bottom” and the meander to the west of “Spring Canyon Point.” What might explain this? (Hint: Consider the processes of erosion associated with both meandering and entrenchment; before entrenchment, was the stream course directly above its current location?)
The following questions are based on Map T-7, the “Canyonlands National Park, Utah” topographic map (scale 1:62,500; contour interval 80 feet), Figures 32-3 and 42-2, stereograms of this region, and Figure 42-1a, an oblique aerial photograph of this area. The map, stereograms, and photograph show the deeply entrenched meanders of the Green River north of Canyonlands National Park, Utah (38°33'40"N, 110°03'16"W). What will be an ideal response?
