I am doing some preliminary research on aeolian/nival landforms in Andes and I came across this:

bright polygonish nets

located at -24.950948, -68.268528 and other locations throughout the Argentinian Dry Andes. Any idea what could these landforms be?

Thanks! V.

It could be some kind of shallow-rooted grasses. A little to the south those features appear to separate into different colors. Though I think this unlikely because your location is in a concave part of the landscape...so unstable for vegetation. change in color further south
