What is the setting of Motel of the Mysteries by David Macaulay?

The book takes place on the United States Continent (Usa) in the year 4022. Much has changed since the twentieth century. For some unknown reason all life on the North American continent as been completely destroyed. For over two thousand years the continent has been left to rot under the pollution and waste what was left behind. In the beginning of the book, Macaulay takes us through several of the most important sites in North America. Now places like New York City and the Arch in St Louis, are seen as religious relics. Litter and overgrown vegetation cover much of the Bigapple Temple as well as triumphal arch.

The rest of the book takes place at the excavation site of the Motel of the Mysteries. It is believed that the site is somewhere on the east coast of Usa.
