Ok...I hate to put an end to the fun but I spent ~5 minutes and figured out what it is... I know, actual investigation makes conspiracy theories boring and its more fun to not put practical effort into it and come up with interesting ideas

One at Kohnen station and you can see the trails that form off of them at an angle to make those patterns.
Some other similar setups from other camps
