The difference between the two areas is that the area around ASU seems
erode less than over by salt verde. It is also in lower elevation. I think they are different
due to human interaction with the area and the river is flowing over by salt verde while
over by ASU the river is not. The river is usually a big factor in erosion. at the rate of
erosion that it is going now it seems like it wouldn't be much deeper since the river is
drying out and that would have a huge effect on the erosion.
