There appears to be a white disc at the end of the removed runway with unnatural dirt patterns. Maybe that's a launch silo? It almost seems like there used to be a runway there to bring in materials and build an underground structure (white disc). The structure does not appear to cast a shadow, potentially indicating that it is flush with the ground.
Why is there a tiny portion of the center of Wyoming that is 3 day service when the surrounding area for hundreds of miles has 4 day service?
