Inverted Channels, North of Juventae Chasma (context frame - MULTISPECTRUM; credits: Lunexit)
|
This image shows raised ridges on a plain to the North of Juventae Chasma. Juventae Chasma, a canyon that is part of the Valles Marineris Canyon System, stretches for about 180 Km (approx. 110 miles) from East to West and about 250 Km (approx. 155 mi) from North to South.
Several examples of raised features have been identified on the plains near this canyon.
In this location, it is most likely that water - either pure or salt water - once flowed through these channels and deposited sediments that eventually filled the channels and became cemented by some chemical precipitating from the flowing water.
Over time, wind eroded the surrounding surface leaving the remnant channels exposed as raised ridges.
