Could it also be explained by saltation[1]? If avalanches can behave like a fluid due to a saltation layer, and saltation can happen to sand particles in wind, then couldn't the streaks be caused by sand/wind instead of water? Any geologists reading that could offer an opinion? Would this part of the article support this hypothesis: > Some of the streaks seem to begin at the tops of ridges, too close to the surface to easily be explained by subsurface aquifers [1] http://en.wikipedia.org/wiki/Saltation_(geology) http://en.wikipedia.org/wiki/Saltation_(geology)
