You are attempting to build a house in a valley bottom, but before you break ground on your new project, you want to make sure that the area is not in danger of experiencing a debris flow. What sort of evidence would you look for to ensure that you would be safe building in that location?
What will be an ideal response?
ANSWER: You would not want to see any of the following evidence of a debris flow: large boulders strewn across the valley floor that could not have been carried by the modern stream in the valley; boulders perched on top of finer-grained deposits; levees of coarse, angular material next to the stream; deep, narrow channels cut in the levees; fan-shaped deposits forming rounded lobes with coarser material at their outer edges; rocks lodged against trees or embedded in bark or branches; scars on tree bark; a drainage basin with large, actively eroding areas; or active faulting.?
