Students at McMaster are spending time in a 3,000-year-old classroom.
Anthropolgy students have set up a dig site at Cootes Paradise.
The site has shown evidence of a connection to the origins of maize agriculture in the area.
Students working there two years ago uncovered a riverbed, thought to be between 10,000 and 30,000 years old. They also discovered a wooden post buried beneath the earth, along what would have been the bank of the river.
Researchers at the site team up with scientists from the university to test excavated items to better understand everything from ancient trade routes and technologies to diet.
Students in the course also spend time cleaning, studying, documenting and cataloguing their finds. So far they have collected arrow heads, military buttons and pottery shards. The students are expected to be on site until early next week.
Here's a look at the anthropolgy students in action, digging through the ancient dirt at Cootes Paradise.
