Tavern site. Additionally, they appear less mobile the Paleo-Indians at the Cardy Site, which used mostly used Moline chert from Illinois, and the group at the Salisbury Steak site, which used chert and sandstone from a variety of sources. One possible explanation for why the two sites in the town of Union featured more local stone material than the Cardy site could be from their occupants using different travel routes. The Niagara Escarpment was a local source of material to make stone tools, and because the bluffs of the escarpment stretch across the western side of the peninsula, Paleo-Indians traveling on the Green Bay side would have come across it. It has been suggested that those living at the Cardy Site may have instead traveled on the east side of the peninsula away from the bluffs. They could have arrived at the Cardy Site from an area to the east of Lake Winnebago where other Moline chert artifacts have been found. The Salisbury Steak site was used as a stone tool workshop, and appears to have been occupied later than the other three sites. The stone materials found at the site come from only a single occupation, and include local material, sandstone coming from the south or west, and chert from the Hudson Bay Lowlands in Canada. How they acquired Canadian stone is unknown, but they could have found it in a glacial deposit, traded for it, or migrated from the far north. As of 2007, seven Clovis points have been found in Door County, and four Gainey points were found at the Cardy Site. The relationship between Gainey points and the more ubiquitous Clovis points is being researched, but there are some similarities. Careful study of certain Paleo-Indian artifacts from western Wisconsin suggests that they were made in the Door Peninsula and carried across the state. Paleo-Indian stone tools from made from stone sourced from the Door Peninsula or its immediate vicinity have been found as far west as in Trempealeau, La Crosse, Jackson, and Jackson, and Monroe counties and as far south as Dane County. Archaeological evidence shows habitation of the peninsula and its islands by several different Native American groups. Artifacts from an ancient village site at Nicolet Bay Beach date to about 400 BC. This site was occupied by various cultures until about 1300 AD. In 246 B.C (±25 years), a dog was buried in a
