A piece of wood peeked out of the sand as she was giving a scuba diving lesson. She didn't think much of it, but she knew what she was talking about.

This is a serious matter. She told her boss that she found a canoe.

The second artifact was discovered in May. She spotted a 1,200-year-old canoe while swimming in the same lake during her day off.

The most recent find is about 3000 years old, according to the group.

She wrote "1000 B.C." on a Post-it note after the results of the radiocarbon dating came back.

She told NPR that it made her think about the people who lived in the area.

The carving of the canoe is from a single piece of white oak. It is thought to be the oldest canoe found in the Great Lakes region.

The two boats were close together. The location and close proximity of the boats suggest that ancient villages may have once existed where Lake Mendota is located, according to experts.

The earliest evidence of water transportation by native tribes in the Great Lakes region is believed to be a 3,000-year old canoe.

The canoe was recovered by members of the Ho-Chunk Nation and Bad River Tribe.

The president of the Ho-Chunk tribe said that the recovery of the canoe shows that the Native people have been here for thousands of years.

The boats will be preserved for two years.

The first systemic search in Lake Mendota is planned to be conducted by archaeologists with the Ho-Chunk Nation.
