I'm interested in this question myself, I don't think Indians ever left physical structures behind, so I looked up a ton on geographical features left behind by Indians and not just in Northeastern and Southeastern America, because there are many types of Indians, but nothing came up on any type of Indian especially in the 1500's. I tried, but I don't think this question can be answered, I looked up this question in many different ways and broke it down to try and gather small pieces of information, but in the end there was no features known to be left behind by American Indians. If anything they left behind culture and methods of doing things. Hope anything I said helps even though I could not figure out the answer.
The African trade in gold and salt caused the Ghana Empire to rise to prominence, and the disruption of that trade led to its decline. During its time, Ghana was one of the richest polities in Africa.Though Ghana was not rich in natural resources itself, it was located along an important trade route between gold- and ivory-producing areas in the south and salt miners in the Sahara desert to the north. As a result of this strategically important location, Ghana became a wealthy entrepot.
Though the exact origins of Ghana are clothed in mystery, tradition places the empire's origins in the fourth century AD. By the ninth century, the area had become affluent according to accounts by Muslim traders who began to visit the area. These traders from the north continued to develop the trade, linking its gold resources with the vital markets in the Mediterranean region, and the empire grew larger by incorporating its neighbors.
The decline of the empire started in the 11th century, when the Almoravids, a militant confederation of Muslims, began to attack the empire and even conquered it for a time. Though their grip on power did not last long, the chaos they brought to the region destabilized trade, hurting the empire's sources of income. Decline ensued. The remnants of Ghana were incorporated into the Mali Empire in 1240.

The Iran hostage crisis ushered in an era in which the greatest foreign policy challenges
facing the United States were the threats posed by conflicts in the Middle East. Today, the United States still finds itself facing similar threats in this region. The wars in Iraq and Afghanistan, diplomatic struggles with Iran, and the ongoing threat
of terrorism continue to create problems for the United States.
