The Sailing Stones of Death Valley have been a scientific curiosity for numerous decades. These rocks seemingly spring to life at various times throughout the year, blazing long trials across the desert’s floor before coming back down to rest. Whilst there have been numerous theories as to what causes this movement, ranging from the plausible to the downright insane, no one had managed to verify just what exactly was going on with these strange rocks. Well now thanks to researchers at the Scripps Institute of Oceanography we now have evidence of just what’s causing this to happen and it’s pretty fascinating.
The video largely supports the theory put forth by Ralph Lorenz some years ago whereby the the rocks are trapped within ice sheets which are then moved by the prevailing winds. What’s interesting about this video is that it shows why the previous experiments, which were largely inconclusive as to ice sheets being responsible, produced the data that they did. It also shows why there seems to be similarities between some movements whilst others seem to be completely random. Pretty much all of these can now be explained by the ice sheets breaking up and bumping off each other, leading to the wide variety of patterns and behaviours.
Like the video says this might not be the most exciting experiment to conduct however it’s always interesting when a long standing phenomena like this finally gets explained. We might not be able to use this knowledge to further other research or develop some novel product, however as we begin to explore further out into our universe knowledge of strange things like this becomes incredibly valuable. When we see phenomena like this elsewhere we’ll be able to deduce that similar processes are in action over there and thus further our understanding of the places we explore.
