Angle of repose

SDG — 3/30/2017 7:56:59 PM (archived)

I was going to comment on how alien the world felt due to such a steep angle of repose of the geology. Really too steep to make sense for a terrestrial mind. Then I read ER's post and realized the angle is an artifact of the stereogrammetry.

Still it makes me wonder what the difference in angle of repose is for similar materials on Earth vs Mars. Logic dictates that it has to be steeper due to less effect of gravity...Googling around I found this interesting post:

not so simple as I initially thought, but a nice rabbit hole to travel for a while.
