Could be those devils.
During the Pathfinder/Sojourner misson, the lander was equipped with a mini weather station.
Scientitist concluded from some of the data that dust devils were passing right over the craft...
The event, in sequence, over a short time, went something like this:
Wind gust in one direction.
Drop in pressure
Wind gust in the opposite direction.
This prompted a few scientists to look over data from the Mars Global Surveyor, where they found the first pics..
One of the Scientists, was my wifes Geology professor.
I had a chat with him a few years ago about this..
The above info is the gist of our conversation..
