In Indiana, post oaks occur almost exclusively in the southern third of the state. Their leaves are variably shaped, but most have five lobes, with the two closest to the stem being smallest. Some observers liken their shape to a Maltese Cross; others call the tree the crucifixion oak. The preserve has a 0.8-mile loop trail with 25 numbered stations and an accompanying brochure. You’ll first pass through a cedar grove, then climb to higher ground where small glades under openings in the forest canopy sport prairie-like vegetation. Lower and moister portions of the preserve are more heavily wooded and feature low limestone outcrops.
Directions: Harrison County. From the intersection of IN 62 and IN 462, south 2.9 miles on IN 462, then left 1.5 miles on Cold Friday Hollow Road to a sign and pull off on the left.
