It was likely the Winooski River that first drew people to the Jericho area, roughly 6000 years ago. Although groups were most likely scattered throughout the Jericho area, most of the artifacts found within the town's borders have been concentrated close to the river.
Dating a bit more recently, between 250 and 3000 years ago, are several larger, more permanent sites and several villages along the Winooski River in Jericho. Artifacts found at these sites reflect a much more sedentary lifestyle, including house structures, pottery shards, bone fragments, and stone tools. There is also a trail that hugs the river in this area.
