VALLES CALDERA VOLCANO: CREDITS, REFERENCES, EXTRA IMAGES

The Valles Caldera appears in many images from US spacecraft -- it is distinctive distinctive, in the US, and at a low enough latitude that all launches from Cape Canaveral pass nearby. Here are a few additional images, and a complete (?) list can be found at David Neal's website.

Base image for the annotated geologic history on the Valles 1 and 2 pages. The Rio Grande (river) cuts north to south (top to bottom) along the east side of the scene. Los Alamos and its National Laboratory are in the center. Paler patches along the mesas are fire scars -- fire is an essential part of the Ponderosa pine woodland ecology.
 
Another Space Shuttle view of the Valles volcano (north= up), this time from overhead and centered on the caldera - the depression in the center of the volcano. The low plains in the caldera are covered with snow, and the higher, tree-covered slopes remain dark or lightly speckled with snow. The gorge of the Rio Grande (river) runs north-south cuts near the right edge of the image

LANDSAT False Color. This false-color image of the Jemez mountains and the Rio Grande valley emphasizes vegetation. Red on this image is brightness in near-infrared light (wavelengths near 1 micrometer), and plants generally are very bright in these wavelengths and relatively dark in visible light. Note the irrigated fields along the Rio Grande and other rivers. Grays and tan colors are rock and desert scrub land. [Red in the image represents brightness in near-infrared light (0.75 to 0.9 micrometers), green in the image represents brightness in red light (0.63-0.69 micrometers, and blue in the image represents brightness in green-yellow light (.525-.605 micrometers)].
