The North Cascades
The North Cascades in Washington are the most alpine region
in the United States outside of Alaska. The mountains are not high,
with most peaks except for the big volcanoes under 10,000 feet, but
they more than make up for this in ruggedness. The mountains rise
from valleys often no more than 1000 to 2000 feet above sea level.
The lower slopes are covered with dense forest, and many glaciers
nestle in cirques below sharp, craggy peaks. The heart of this
wilderness is contained in North Cascades National Park and the
Glacier Peak and Pasayten Wilderness Areas.
Mount Logan, just northeast of Cascade Pass, is one of the major
peaks in North Cascade National Park. It is a massive mountain, about
9100 feet high, with several glaciers, including the Douglas Glacier
on the east and the Fremont Glacier on the west. The Mount Logan
7.5 minute DEM was made by digitizing a contour map, and thus is
relatively accurate. The valley to the north of Mount Logan is that of
Fisher Creek, and the high ridge north of Fisher Creek is Ragged Ridge.
Load the CascadesN.DEMset file when you save a Panorama data file
from the Georama program in order to set up the rendering appropriately.
