Arrows point to junks of ice that moved down a sand dune to form channels, as seen by HiRISE.
Summary
[edit]
| Description |
English: The caption from NASA explains the picture thusly: When we took this image, spring was slowly returning to the Southern Hemisphere. These sand dunes, within Kaiser Crater, are partially covered with carbon dioxide ice. Numerous channels going down the face of the dune are caused by blocks of ice sliding down the slope.
The alcoves of the channels on the right have blocks of ice waiting to be released by the warming sun. In the channels bright spots mark what we think are blocks already sliding down. |
