Did a search of the term archaeology on Goolgle correlate and came up with this interesting map. It is the distribution of google searches for the term archaeology and archaeological across US states.
There is a strong search for those terms in the west. From the google correlate website I can not tell if this represents out of the total US or relative to state. If it is out of the total US that is amazing since those states that score the highest also have some of the smallest populations. If not it still shows that there is a pretty big interest in the west (excluding the coasts in archaeology) or at least for searching for the term archaeology.
