Knob Lake Trail Professional Guide
Detailed Trail Description from our Guidebook
"A loop hike, with a linear spur near the finish, that includes climbs up some of the highest hills in the Jackson-Washington State Forest. The path is narrow but easy to follow, and it is not often a busy place. The north-facing slope of the preserve, where Trail 5 is located, provides the moist environment necessary to the yellowwood, a tree found only in a few places in Indiana.
Yellowwood is not a common tree anywhere, but is found more often in the cool forests of southern Appalachia and the Ozarks. With little indication of reproduction, it is listed as a threatened species in Indiana. Two of the 22 interpretive signposts on Trail 5 identify the rare tree, whose smooth, gray bark is similar in appearance to a beech tree. The
yellowwood is smaller, however, and grows at an angle, producing clusters of pealike flowers every other year."
