<br />FIGURE 3. --Sketches. not to scale, of (A) perspective view
<br />of a debris cone and (B) profile of c""'ne area.
<br />
<br />Ordinarily. inhabitation cr development begins near the toe
<br />of the cone and progresses upward on the cone until halted by
<br />a large flood; or. if mainly agricultural, development begins
<br />for the sake of the water near where the stream leaves the
<br />mountain, with habit.ations located where flood flows are
<br />hopefully not expected.
