58 Virtual Field Trip: Marcus
Landslide questions and
answers
The Marcus Landslide is about 1 kilometers long. - answer What is
the length of the landslide? You can use Google Earth or Acme
Mapper to assess how far the landslide traveled from the McDowell
Mountains. This is where the McDowell Mountains end: N 33.68150
W 111.79158l
The Marcus Landslide is about 1 kilometers long.
The Marcus Landslide is about 1 mile long.
The Marcus Landslide is about 500 meters long.
The Marcus Landslide is about 100 meters long.
about 500 meters - answer What is the width of the landslide
deposit, measured at this location: N 33.68214 W 111.78614?
about 500 meters
about 30 meters
about 1200 meters
about 100 meters
about 10 meters thick - answer What is the thickness of the
landslide?
If you are knowledgeable about Google Earth Pro and know how to
make a path to measure an elevation profile, this should be a quick
estimate. You simply make several paths across the landslide (south
to north) and look carefully at the elevation change. You should be
able to pick the correct answer pretty quickly.
, Another way to measure the thickness is to use the topographic
map information in Acme Mapper. In order to approximate the
thickness, you will need to compare the elevations on top of the
landslide with the elevation of the adjacent land surface. For
example, if you compare this location on the landslide (N 33.68330
W 111.78757, elevation of about 793 m) with this location on the
surface just to the north (N 33.68440 W 111.78753, elevation of
about 776 m), the landslide is about 793-776 or 17 m thick at this
spot.
If you do this at 3 to 5 spots below and then you should be able to
pick the correct answer.
