Unless it was apart of some MAJOR HISTORICAL SUGNIFIGANCE, I see no point in not developing an area. Every section of the world holds some history, but to not utilize the land is just crazy. Imagine if Europe or the middle east was never built, It has roman and other cultures relics all over it. it does no body any good to let the land go farrow. If it is of significance, then excavate it and get it over with.
