Title Geology of the DeGray Spillway, Arkansas: A Geologic Excursion Through Rocks Deposited in an Ancient Ocean Basin
Author (s) Roger M. Slatt and Charles G. Stone
Date 2010
 
General Description

The outcrop you are about to see is a truly unique section of sedimentary rocks. More than one thousand feet of rock section is continuously exposed in the spillway at Lake DeGray. The Geo-Trek Interpretive Trail is provided by the U.S. Army Corp of Engineers and the Clark County Strategic Plan. Geologic interpretation (of this section) of exposed rock is provided by the Arkansas Geological Survey, Little Rock, Arkansas and the University of Oklahoma, Norman, Oklahoma.

The U.S. Army Corp of Engineers water project at DeGray Lake has additional value as a geologic workshop. The spillway, dam, and associated structures are viewed by many people yearly. This group includes geologists, engineers, students of all ages, and rock enthusiast. Many visitors will return more than once. In fact, the spillway exposure is considered as a world class example of deep water sedimentary deposition. Much study has gone into the geologic interpretation of these exposures. Many similarities exist between the Pennsylvanian Jackfork Formation and the deep water sedimentary deposits being explored for oil and gas today.
