What is the main conflict in The Mound Builders by Lanford Wilson?

The play explores the conflicts between a team of visiting archeologists who are excavating several early Mississippian mounds and a local man who hopes to make his fortune by developing the land where the mounds are located. As the archeologists ponder and celebrate the dignity of the pre-Columbian people who built the mounds, they overlook the humanity of the people alive around them.
