(CNN) -- In Bell County, Texas, archaeologists are hoping to find evidence that humans roamed North America 1,000 years earlier than what is presently believed.

Conventional theory holds that the so-called Clovis people first came to the Americas across a land-bridge from Asia about 11,500 years ago. However, the discovery of a site in South America has raised questions about that theory and started archeologists like Michael Collins on a quest to find evidence of pre-Clovis people in North America.

"We see hints, whispers that maybe there are earlier cultural remains there... can't say for sure yet," said Collins, an archaeologist from the University of Texas.

But, Collins has found an artifact-rich site where Clovis people apparently returned -- again and again.
