geysers
Also if these were geysers the ground would quickly become dirty wth the material coming out. The ground here though is quite clean. Unless of course this is a "Kodak moment" when the geysers just all started which is extremely unlikely. I think this indicates two wind directions which makes streaks in two different directions. Here's a good example of streaks in one direction. You can see the streak is flat on the ground by the way it covers the spiders, and of course these photos are taken from directly overhead.
