Here is my hypothesis, which is somewhat similar to that of one reader (Will). At some point, there was freshly fallen snow on the ridge, which was packed down by an animal. Eventually, the wind increased, and the freshly fallen snow was more easily removed than the packed snow, leaving the trail of snow pedestals above.
Will suggest that it could have been a deer, but the lack of a second set of parallel tracks suggests it may have been a different animal. One possible candidate is the long-tailed weasel, which I occasionally see in the high mountains of Utah, even in winter (although in winter, they are usually white, in contrast to the photo below).

There may be some other candidates as well...or maybe better hypotheses.
