Surveying of Martian landscape
In order to have a reasonable and traceable survey and aerial identification/observation of strange feature, evident in these photos , we need to have a coordinate grid pattern established and each area photographed in a Martian annual cycle, at a say 12 equal intervals of time, similar to an earth like month. In this way ny feature that are seasonal will be readily identified.
The elements subject to wind erosion will then be separated from geological features. Satellite base imaging and technique such as spectroscopy will show the composition of the flumes and other unearth like phenomena.
