Geomorphology Of Icy Debris Fans: Delivery Of Ice And Sediment To Valley Glaciers Decoupled From Icecaps, R. Craig Kochel, Jeffrey M. Trop, Robert W. Jacob
Geomorphology Of Icy Debris Fans: Delivery Of Ice And Sediment To Valley Glaciers Decoupled From Icecaps, R. Craig Kochel, Jeffrey M. Trop, Robert W. Jacob
Faculty Journal Articles
The pace and volume of mass flow processes contributing ice and sediment to icy debris fans (IDFs) were documented at sites in Alaska and New Zealand by integrating field observations, drone and time-lapse imagery, ground penetrating radar, and terrestrial laser scanning. Largely unstudied, IDFs are supraglacial landforms at the mouths of bedrock catchments between valley glaciers and icecaps. Time-lapse imagery recorded 300–2300 events reaching 15 fans during intervals from nine months to two years. Field observations noted hundreds of deposits trapped within catchments weekly that were later remobilized onto fans. Deposits were mapped on images taken three to four times …

Map and Chart--KGS
Cumberland Gap National Historical Park is located in parts of Kentucky, Virginia, and Tennessee. The park was authorized by President Franklin Roosevelt on June 11, 1940, and is now the largest historical park in the National Park System. It contains 24,000 acres along Cumberland Mountain near Ewing, Va., proceeding southwest toward Fern Lake in Tennessee, a distance of approximately 20 miles. The average width of the park is only 1.6 miles.
The park hosts a distinctive range of geologic processes and features. Unique structural geology, caves and karst, surface and groundwater erosion, and mass wasting are just a few of …
