Located in the Clinch River watershed, Pinnacle Natural Area Preserve follows Big Cedar Creek to its confluence with the Clinch River. This site is named after The Pinnacle which is a 300-foot towering outcrop of dolomite. In addition to its namesake, this site holds fascinating geological features including numerous waterfalls and cavern formations. A trail follows Big Cedar Creek and ascends towards the Pinnacle. Habitats within this area are typical of mesic slope forests, there are rich coves and dry calcareous woodland communities. The plethora of water from the creek and springs attract amphibians such as green and pickerel frogs. Salamanders require a little more investigation, but turning over a few rocks near springs can produce mountain dusky and northern spring salamanders. In addition to the wonderful diversity of fauna, this site serves as residence to a number of rare and unusual plants including American harebell, Canby’s mountain-lover, and glade spurge. The Big Cedar Creek millipede is only known to exist here and a few nearby areas, and can sometimes be spied around rock ledges.
