[edit] Richat Structure

The Richat Structure in Mauritania is not an impact crater, but rather a eroded anticline. It is 50km across, and shown in here in a topographic reconstruction (scaled 6:1 on the vertical axis) from sattelite photos. False coloring as follows: bedrock=brown, sand=yellow/white, vegetation=green, salty sediments=blue

This highly detailed image, reconstructed from sattelite photographs, is aesthetically pleasing and shows many geological features, such as parallel dunes, erosion gullies, cliffs, and of course, the eroded anticline. It appears in Mauritania and Richat Structure. NASA created the image - so, public domain. Oh, and high res, and no blown highlights I can see.

  • Comment I've uploaded a version that I downsampled from the tiff. It has less artifacts. Due to the nature of the image, there's all sorts of aliasing going on. [1] --DonES 06:43, 20 November 2006 (UTC)
  • Thank you for that DonES. I had just downloaded the tif and planned to do so myself. Debivort 07:43, 20 November 2006 (UTC)
  • Support. Excellent nomination, incredible image. I saw almost no artifacts in full-size. --Janke | Talk 07:21, 20 November 2006 (UTC)
