Oh, sure, the technical means to install it are not uncommon. Nor are the materials. Sadly, since it's on federal land (illegally so) it will probably have to be removed. And our local news media has reported that it has already been defaced and damaged.
I'm conflicted about that. I choose to live where I do because of literally giant swathes of unspoiled land, desolate though it may be. But the holiness of the land isn't pure. To the west of my city there is the famous salt flats that appear in so many films. That's already spoiled by the Bonneville Speedway. To the north of that, Hill Air Force Base maintains a bombing range, closed to the public for obvious reasons. There we pound large portions of Utah landscape into dust and rock fragments on a daily basis. So when someone takes half a square meter in an 800-square-kilometer patch of desert and does something with it that creates some buzz and admiration, I would kind of like it to be left there. But then if you leave that one there, you have to leave all of the subsequent ones there, including the ones that have little artistic or technical merit.
We have similar installations elsewhere. One of the day trips I commonly do for visitors combines the Golden Spike visitor's center, the factory where the space shuttle boosters were made, and the Spiral Jetty, an earthwork art installation on the north shore of the Great Salt Lake. Then for rail fans, the railroading museum in Ogden and dinner at Union Station.
