Does the Spiral Jetty make the Great Salt Lake a museum?

A widely debated topic in the museum world is whether or not the Spiral Jetty in the Great Salt Lake makes the Great Salt Lake a museum. In my opinion, it does not. True, the Spiral Jetty is a work of art and can be used to teach others about subjects such as marine construction, the artist, and the Great Salt Lake, and the Spiral Jetty is found in the Great Salt Lake, but one way the word "museum" can be defined is as a building (or area) that puts many different exhibits on display. If the Great Salt Lake is examined with this definition in mind, it most definitely falls short. The Spiral Jetty is just one exhibit, one display of artwork, available for viewing, thus leaving the lake just a lake, not a museum. Thus, the Great Salt Lake can not be a museum, but rather just a lake that houses a piece of work. This is not to say that museums must be a constructed building. In contrast, this definition only mandates that a museum must include many different works of "art" or exhibits for inspection. And so, my opinion on the matter, is that the Great Salt Lake, even with the Spiral Jetty included in it's boundaries, should not be considered to be a museum.
