Greater Green River Intergalactic Spaceport

The Greater Green River Intergalactic Spaceport is a small public use airstrip about five miles south of Green River, Wyoming on a mountain known as South Hill.  On July 5, 1994 Resolution R94-23 of the Green River city council designated this landing field as the "Greater Green River Intergalactic Spaceport", for inhabitants of Jupiter who might wish to take sanctuary in Green River in the event their planet is threatened by collisions from comets or meteors, in apparent reference to the contemporary Comet Shoemaker–Levy 9 impact. No spacecraft have yet to use the spaceport, and actual use has been limited to terrestrial aircraft.
