Comparison to boats brings to mind the high prows and streamlined forms of Viking longboats, shaped for hydrodynamic efficiency as yardangs are efficiently shaped by the aerodynamics of sand: http://www.markland.org/docs/shipphysics.pdf
Photos 3 and 4 resemble oncoming fleets, a dire sighting from any medieval coast.

I guess that it's all about fluid dynamics - regardless of what the fluid is.

So, a herd of benign beasts or an invading fleet? Any other imagery stimulated by these humble yardangs?
