Two GREAT views of the Grand Canyon and Bandelier NM and environment. Arizonans, I'd like you to check the larger version of the Arizona image and see if you can identify a particular weird feature. (See below the image for my question.) Click on each image to see the larger version.
Grand Canyon in Snow (Larger version is 2.1 MB.)
In the larger version, to the west of the lower Grand Canyon and southeast of Lake Mohave and a small mountain range, there's a flat light-brown patch. Does anyone know what that is, or is it an image artifact?
Bandelier National Monument and environs
Since I'm a volcano guy... in the upper left portion of this image is the Jemez caldera, one of the largest calderas in the world and certainly the largest in the U.S. The semi-circular features around it are resurgent domes (like the one inside the Mt. St. Helens crater). The dissected valley terrain southeast of the caldera, flowing down to the Rio Grande (part of which Los Alamos is on) is the eroded Bandelier Tuff, deposited in a massive supervolcanic eruption. The Bandelier NM cliff dwellings are made out of the Bandelier tuff.
Sheesh! You didn't ping me to the thread?
:-)
Nice to have things getting back to normal, eh? Maybe we'll get a nice, calm vaccination or fluoridation thread pop up soon. ;-)
Hope things are well with you.
