Northern Grand Canyon (Week 7 Lab)

I selected a section of the Northern Grand Canyon in Arizona, U.S. because, it not only has great features in terms of varying elevation (cliffs, peaks, and small valleys), it's easily recognizable as one of the most well known features on the Earth. Digital Elevation Models have a large scale of uses. These programs can be used for studying habitats. This could help scientists get a good idea of the kind of wildlife that could live within the area. They can also be used to study vegetation, and in this particular case the elevation could answer why plants are scarce in the Grand Canyon. Animal migrations can be studied through this because the elevation differences in the land can imply the future temperatures in the area in different seasons. The program could also be useful as references for natural disasters. Such as the effects of a flash flood (which would be very interesting in this particular area), the possibility of a tornado (which would be pretty low in the grand canyon), and the changes in seismic activity (for example: if a magma chamber existed underground, it would create changes in elevation in the land above it like Yellowstone National Park).
The GCS (Geographic Coordinate System): GCS_North American_1983 is the spatial reference.
