Ithan Valley Park is a remnant piece of an old estate which was left when the Blue Route was put together. A mill predated the estate, remains of which are located near the parking area. The owners of the Mill and the Estate were keenly interested in botany and collected trees from both North America and the Old World. A group was formed to identify any trees that are either old enough to have been part of the original collection or seedlings of those trees. Yellow tape was placed around 22 trees (listed below) which are numbered and roughly located taking the old driveway up from the parking area.
