The area I selected covers the area:
37.4038888882 degrees North latitude to
37.1580555548 degrees North latitude
and
118.483611111 degrees West longitude to
118.193055555 degrees West longitude
to an extent of 0.017453292519943295 degrees.
The area I picked lies in the Sierra Nevada Mountain range in southeastern California near to the bend in Nevada. I selected this area due to its mountainous terrain, knowing that it would provide a stunning visual display on a 3D model, shaded relief model, slope map, and aspect map. Mountainous terrain is typically accompanied by a number of valleys in between the mountain peaks, providing for relief when put on any of the above-mentioned maps. Additionally, I had just gone camping in the Yosemite Valley near to this location which gives added significance to this map for me. The drastic changes in elevation can be seen in the maps below.
