Mount Rainier and Vicinity
Mount Rainier is the biggest of a series of volcanos dotting
the Cascade Range from northern California to the Canadian border.
These volcanos are part of the "ring of fire" around the Pacific
Ocean caused by subduction of the oceanic crust. Mount Rainier
has been active within the last thousand years, and if it were to
come to life again the results could be far more devastating to
human life and property than the explosion of Mount Saint Helens
in 1980. The main danger is from mud flows racing down the valleys
that drain Mount Rainier.
Mount Rainier is near the center of the "YakimaW02" subquadrangle,
and dwarfs all the mountains around it. Some of the nearby mountains
to the south and to the northeast reach 7,000 feet. The Crystal
Mountain Ski Area is in the mountains to the northeast. Major river
valleys include the Nisqually draining the southwest part of Mount
Rainier and the White draining the north side.
Each one degree by one degree quadrangle is split up, at this
lattitude, into nine subquadrangles. The two digits at the end of the
subquadrangle file name locate the subquadrangle within the one degree
quadrangle. The first digit varies from 0 at the west edge of the
quadrangle to 2 at the east edge of the quadrangle. The second digit
varies from 0 at the south edge of the quadrangle to 2 at the north
edge of the quadrangle. The points in the DEMs are spaced every 3
seconds of arc in lattitude from south to north and every 3 seconds of
arc in longitude from west to east. At this lattitude, 47 degrees
North, the physical separation of the points in the East-West direction
is about 64 meters, compared to the separation in the North-South
direction of 93 meters.
Try using the CascadesS.DEMset file when you save a Panorama data
file from GeoRama. But feel free to experiment with other settings
of the rendering parameters.
