FRONT AND BACK COVERS: Portions of the Las Vegas,
Nevada-Arizona-California, color-infrared satellite image
map, the first to be computer-mosaicked by the U.S.
Geological Survey from satellite-acquired multispectral
scanner data and printed in a standard 1:250.OOO-scale
quadrangle format. The data were collected in October 198!
from a height of about 570 miles above the Earth's surface.
The view of Las Vegas (front cover) includes partially
vegetated (dark red) and grassy (bright red) urban areas.
Asphalt-covered roads' and airport runways are black. The
white area to the northeast of the city is a playa. Sparsely
vegetated rocky and soil-covered areas range in color from
beige to dark greenish-gray depending on the composition
and the texture. The view of Toiyahe National Forest (back
cover) shows snow on Charleston Peak above the coniferous
forests (dark red). The yellow areas east of the La Madre
Mountain are naturally red rock outcrops.
