NASHVILLE – The Department of Environment and Conservation’s Resource Management Division will host a guided Twin Arches Trail Hike at Big South Fork on Saturday, July 31.
This hike will feature the endangered Cumberland sandwort and other rock-shelter species. Hikers will take the 1.4-mile loop trail that goes around the arches and also hike a short “out and back” portion of the Twin Arches Loop Trail that goes in and out of several rock shelters for another 1.4 miles. With a total of 2.8 miles, this hike is rated moderate.
These arches form the largest natural bridge complex known in Tennessee and also represent one of the world's largest. The two sandstone arches are situated end-to-end, and are commonly referred to as the North and South Arches. The tops of the arches support vegetation adapted to dry conditions and include a mixed pine/oak/heath community – a fragile, moss-lichen community and sandstone barrens scattered along the top of the gorge bluffs that support populations of needlegrass, little bluestem, and blazing star.
In the protected environment of some rock shelters and growing in sand, are a number of rare species, such as Cumberland sandwort and Lucy Braun's white snakeroot. Only a few other plant species regularly grow in these habitats. Division Botanists David Lincicome and Andrea Bishop will serve as hike leaders.
Space is limited to 20 hikers and reservations and reliable contact information are required. To reserve a space on the hike, please commit or cancel by July 28 by contacting Andrea Bishop at (615) 741-9141 work, (615) 804-7999 cell or andrea.bishop@.tn.gov. If inclement weather is forecasted, the hike will be canceled.
