Attendees


Eight people left Knoxville on a rain predicted Saturday morning to Big South Fork National River and Recreation Area in Oneida, Tennessee. At park headquarters in Bandy Creek, members met National Park Service (NPS) geologist and field trip leader Todd Knoedler, temporary NPS employee and ETGS member Chad Harrold, and NPS historian Tom Des Jean.

In heaquarters basement, park historian Tom Des Jean exhibited a large display of rocks and fossils found in the Big South Fork. Included in the display were samples of crude oil collected from some of the original oil wells at Big South Fork.

The group then traveled to the Bandy Creek Gorge, Bandy Creek Overlook, road cut of a Mississippian and Pennsylvanian contact, bridge showing oil seepage into the Cumberland River, Former Blue Heron Coal Mine, and Split Bow Arch Overlook. Stops included bedrock formation contacts, coal mine reclamation results, and infrequently visited arches and over-hangs resulting from weathering and erosion.
