Villages and bygone villages
Garfield is located in the northeast corner of Hyde Park. In the late 1800s, Garfield was a village with a store, a post office, a school, and two sawmills. In 1922 the sawmill owned by Charles William Manning burned down and he decided not to replace it, causing the loss of many jobs. Residents began to leave Garfield. Eventually their abandoned farms reverted to wilderness. The area remains thickly wooded and sparsely developed to this day. It is best known as the Morrisvilleturnoff point for the Green River Reservoir State Park.
