Line 10:
The process starts with the dark dune spots which form in early spring. Here are some examples in [[Richardson (Martian crater)|Richardson Crater]] in the Martian southern hemisphere- one of the places where the Flow Like Features (FLFs) have been observed.
These are thought to result from the [[Geyser (Mars)|Martian Geysers]].
The idea is that a semi-transparent solid such as dry ice or clear ice acts like a greenhouse to warm up a layer below the surface (the "solid state greenhouse effect"). When this lower layer consists of dry ice, then it turns into gas and as the pressure builds up, eventually escapes to the surface explosively as a Martian Geyser.
