2018 Annual Meeting and Field Trip

Old Wine in New Bottles

Active tectonics and landslides

in an ancient orogen

Headquarters:  Boone, NC

Dates: October 5-7, 2018

Field trip leaders: Rick Wooten, Kevin Stewart, and Jesse Hill

The 79th meeting of the Carolina Geological Society will be held October 5-7, 2018 in the area of Boone, NC, under the leadership of:

Rick Wooten (North Carolina Geological Survey)

Kevin Stewart (University of North Carolina - Chapel Hill)

Jesse Hill University of North Carolina - Chapel Hill)

Ellen Cowan (Appalachian State University)

Keith Seramur (Appalachian State University)

Anne Witt (Virginia Division of Mineral Resources).

The one and a half day field trip will examine the relationships between tectonic history, landscape evolution and slope movement processes - faults, lineaments, rock slides and debris flows.


This trip examines the construction of the geospatial legacy of the August 13-14, 1940 tropical cyclone in Watauga County: impacts of the storm as seen on the current landscape – lessons from the past for the future.  Landslide hazard mapping in Watauga County identified over 2,100 landslides, mainly debris, flows, that were triggered by rainfall from a tropical cyclone that passed over the area during August 13-14, 1940. 

1.Debris flows had direct impacts on a total area about 3.68km2 (1.42mi2), 

2.Landslides killed 14 people, destroyed or damaged 32 structures and severed U.S. 421 in 21 places. 

  1. 3.Floods destroyed 90% of the bridges

What We Will See (in no particular order)

Extent and areas affected by debris flows triggered by rainfall from the August 13-14, 1940 tropical cyclone: 

Remnants of the 1940 debris flow scars and deposits and related geomorphology.

Pleistocene debris fan deposits (footslope of Rich Mountain)

Contaminated site involving Pleistocene debris fan deposits and saprolite.  Investigation of contaminant migration through a diamictons/saprolite aquifer on the footslope of Rich Mountain.

Influences of bedrock structure on the Blue Ridge Escarpment (Deep Gap re-entrant) and debris flow occurrence.

Mesoproterozoic metaplutonic rocks and Neoproterozoic metasediments within the Grandfather Mountain Window.  Mesoproterozoic basement gneisses and Neoproterozoic-early Paleozoic metasediments in the overlying Fork Ridge and Gossan Lead thrusts sheets.

Bedrock structures and fabrics related to rock slope stability along the Linville Falls and Boone faults, including a stop at the Vulcan Materials Boone Quarry.

Active, slow-moving, weathered-rock slide (Hwy 105 near Old Watauga High School)
