Fluid Fans?

  • itsanty by itsanty

    These fans look like the deposits have spread out via a fluid rather than via wind. I accept that a sharp change in wind direction would whisp deposits in an uneven pattern but some of the frongs in these fans closelt follow the contours of the land, has this been seen elsewhere?

    Hi!

    Yes, we see these in many locations, on polar dunes for example. Most scientists believe these are dry seepage or dry flow - dark dust runs down the icy slope. In this particular place it's impossible to have liquid water, the surface measures -123degC.
