Snowboarding on Mars? Gullies by Cascades of Dry Ice

Mars' surface is streaked with furrows and ditches across its rusty 
red soil, mimicking our planet's river plains. But unlike Earth, Mars 
has no surface rivers or streams that would leave such marks.

These signature gullies on its 
red sand dunes are a result of cascades of dry ice running across the planet's surface every Spring.
