Discover an Ancient City or Ruins

I have been to some of the great ruins & ancient cities in North America & South America. Machi Picchu in Peru, Tiawaniku in Bolivia, Tikal in Guatemala, Copan in Honduras, & Palanque in Chipas; which is in Southern Mexico. Some ruins I had to take a boat to reach the ruins; Yaxchilan in Mexico is one of them. There are 1000s of Mayan cities in Mexico & Central America; & 100s more to be discovered. Peru & Bolivia also fasinated me,esp. The Andes Mountains & the eastern slopes which leads out to the Amazon. Its time to explore.
