3D Elevation Map - Devil's Lake State Park,
Wisconsin - Looking East (N43° 25.0' W89° 44.0')
Devil's Lake was formed during the last Ice
Age, which ended about 10,000 years ago. Vast ice sheets up to
two miles in height advanced across Wisconsin. One lobe of the
glacier reached its furthest extent here, wrapping around the
facing 500-foot bluff. The terminal moraine of rock and gravel
dumped by the glacier plugged what was once the channel of an
ancient river. Devil's Lake formed where the channel was not filled
with glacial debris.
This elevation map was made with Manifold
System 5, a comprehensive GIS program. A 2D gray scale orthophoto
was used as a transparent overlay on the terrain model generated
from a 30-meter USGS DEM. Here's another
